JRSO—LIMS Viewer (LIVE) User Guide

Table of Contents

Introduction

LIMS Viewer (LIVE) is a Web-based application that allows users to retrieve sample information and analytical data from the Laboratory Information Management System (LIMS) database and display them in a graphical format. This tool is a replacement for the LIMSPeak viewer, as the technology behind the old program could no longer be supported.

User Account Privileges

All shipboard participants can use LIVE to view data on the ship during an expedition, as no data on board are flagged as moratorium. After the cruise, users can view post-moratorium data freely; a login is required to view moratorium data.
Users with LIVE editing privileges (technical personnel) can define new panels and templates. LIVE editors must have basic understanding of the LIMS database components and data structure. More information on panel and template control and maintenance can be found in later sections of this manual.

General User Instructions

LIVE can be found on the ship on the applications page, or at web.ship.iodp.tamu.edu/LIVE. On shore, it can be found at web.iodp.tamu.edu/LIVE.
LIVE is optimized for use in the FireFox browser. For best results, use FireFox on either a Mac or PC.
The LIVE main screen is divided into control bar (top) and data display (bottom) areas (Figure 1). 

Definitions

Panel: A single region (plot) in the data display area. Panel types include: depth panel, recovery panel, data panels, image panels, sample panels, and lithology panels.

• Data panel: A plot that shows measured data values as symbols and/or lines and/or as text values. Multiple data sets can be shown on a single panel.
• Image panel: A panel that shows images of two types:
  • Depth-referenced images such as section-half or whole-round 360° images
  • Thumbnail images such as close-up photographs, microscope photo images, thin section photomicrographs, or SEM photomicrographs
• Sample panel: A panel that shows sample information (sample type, test code, request code, sample name, etc.) as area and/or text labels.
• Lithology panel: A panel that shows depth-referenced lithology descriptions (lithology prefix, principal lithology, or lithology suffix) as area and/or text labels.

Template: A collection of panels assembled into a single data query and data display. A template always includes depth columns and recovery panel and may have any number or type of other panels to the right of the recovery panel.

LIVE Control Bar

The main screen control area is divided into four sections

.

Title Bar: The top blue bar (

Figure 1) is the title bar and controls data view functions:

• The date/time

• stamp Version indicates the update version of the application
• View Data button: runs the query
• The timer next to View Data counts the time from when the button was last clicked (last database query)
• Unzoom button: restores full query view without re-querying database
• Break checkboxes: toggles section and/or whole-round break indicator lines across data plots in the data viewing area
• Login/Logout controls
• Links to the IODP applications page

• and this user guide

Template Selector: The left-hand gray area (

Figure 1,

) is the template* selector (*required field):

• Available templates are shown in the drop-down list. The template name indicates what data/sample/image panels are included on the data display or may indicate a specific quality control template (Box_Corese.g. READY TO SPLIT).
• Templates are available for most common user queries. Contact technical staff if no template contains the data combinations desired.
• The selected template is applied to the database query when the View Data button is clicked. After the query is completed, selecting a different template does nothing unless View Data is clicked again.

Query Filters: The center gray area (

Figure 1) contains the query filter controls (Site* and Hole* are required fields):

• A minimum of a

• Site and

• Hole must be selected from the drop-down lists. If an expedition is selected first, only

• Sites from that expedition are available on the drop-down list, and when a

• Site is selected, only valid

• Holes from that

• Site appear on the drop-down list.
• To use the additional filters in this area to narrow the data query, see Query Filters below.
• These fields are applied to the database query when the View Data button is clicked. After the query is completed, changing the filters in this area does nothing unless View Data is clicked again.

Note: The values in these fields are "sticky," meaning that they will remain as selected until changed by the user, or the browser is refreshed. This allows a user to switch templates and re-query to view a different data set using the same filter parameters.

Post-Query Filters: The right-hand gray area (

Figure 1) accesses

Post-

Query filters.

• Changing these values changes the displayed values accordingly (see Post-Query Filters, below).

Note: These values are "sticky," meaning that they will remain as selected until changed by the user or the browser is refreshed. This allows the user to change query parameters and

re-query using the same sample and/or data filters.

Basic Workflow

Figure 2

 shows the initial LIVE screen before any items are selected. The minimum workflow is as follows:

1. Select a template from the pull-down list.
2. Select at least a

1. Site and

1. Hole;

1. Expedition is an optional field.
2. To see data for the entire selected

1. Hole, click View Data

1. .

2. After a brief pause, the data will display with depth columns and recovery panel, along with image, data, sample, or lithology panels specified in that template (Figure 3).

Query Filters

Query filters are used to restrict the amount of data queried (instead of viewing the entire hole). These filters are applied before the query, meaning that in order to see them applied, the data must be queried from the LIMS by clicking View Data.

Core Filter: Enter a top core and/or bottom core to query a specific range of cores.

• Specifying only a top core retrieves data from the specified core to the bottom of the hole.
• Specifying only a bottom core retrieves data from the top of the hole to the core specified.

Depth Filter: Enter top depth and/or bottom depth to restrict the data query to a specific depth range. The depth function is inclusive, so slightly more information than the strict depth range may be returned.

• Specifying only a top depth (in meters) retrieves data from the specified top depth to the bottom of the hole.
• Specifying only a bottom depth (in meters) retrieves data from the top of the hole to the depth specified.
  
  

Depth Scale Filter: The default query is CSF-A, and CSF-B is available for any data set. If a composite depth scale is available in LIMS for the selected hole, it will appear on the drop-down list. Depth scale filters may be useful if there are overlaps in cores or sections (indicated by darker shading in the recovery panel).

• The CSF-B depth scale squeezes expanded material into the drilled interval, thus preventing overlap.
• For any core with recovery of ≤100%, CSF-B and CSF-A are the same.
• For any core with recovery >100%, CSF-B compresses the core to fit the drilled interval. This compression is linear across a core, not necessarily proportional to the actual expansion that occurred.
• A composite depth scale (CCSF) is created by the stratigraphic correlators by shifting core depths to remove overlaps. If the user selects a composite depth scale, the depth of any given core may be altered from its drilled depth. Some composite depth scale queries may return overlapping cores.

Display Filter: The display flag filter applies only to section half and section whole-round images and is primarily useful to IODP technicians as a quality control check.

• Display flag filter default is T (true).
• Display flag alternate options are "false" and "null" (blank). The latter queries image files for which the display flag is either true or false (all images).

Post-Query Filters

In addition to the filters applied before a query (core range, depth range, depth scale, and display flag), filters may be applied post-query using the Data Filters and Sample Filters buttons. Each type of filter applies only to its applicable data type; filtering by sample type in the sample filter will not affect any panels displaying analytical data.

• Post-query filters are only applied to displayed data after the Apply button within the filter selector is clicked. Filter selections can be canceled by clicking Cancel in the filter selector window.
• Post-query filters can be cleared by clicking Clear filters and Apply within the filter selector window. Note that clicking Clear filters without then clicking Apply will do nothing.

Data Filters

 Data filters apply to data panels but are not applied to sample panels (Figure

4).

• Data may be filtered by sample type, shipboard test code, and/or by sample name.
• To select data filters, click the Data filters button to open the data filters window and make the desired selections for Sample type and/or Test code and/or type in a Sample name.
• Click Apply to apply the changes to the graphic panels or Cancel to abort. Applied filters will be listed below the Data filters button in the post-query filter area.
• To clear all selected data filters, click Clear filters then Apply. The list of filters under the Data filters button will disappear and graphic panels will revert to the original query parameters.

4. Data filter window. 

Sample Filters

 Sample filters apply only to sample panels (Figure

5).

• Sample data may be filtered by sample type, shipboard test code, sample name, request number, and/or request code.
• To select sample filters, click the Sample filters button to open the sample filters window and make the desired selections for Sample type and/or Test code and/or type in a Sample name, Request number, and/or Request code.
• Click Apply to apply the changes to the graphic panels or Cancel to abort. Applied filters will be listed below the Sample filters button in the post-query filter area.
• To clear all selected sample filters, click Clear filters and then Apply. The list of filters under the Sample filters button will disappear and graphic panels will revert to the original query parameters.

Results Display

Navigation and Control

Once data are retrieved, a number of methods of navigation for viewing data exist. In each case, navigation does not run another query but instead uses the data already retrieved. In this way, a user may zoom in to a region of interest and then zoom back out (to a maximum of the full scale of the originally-retrieved data; Unzoom) without having to wait for a database query to run.

Depth Navigation Bar

The left-most panel in the data area shows the depth columns, divided into two areas as shown in Figure

6.

Upper Image:

the darker-shaded area in the first column is the depth navigation bar, which always shows the top and bottom depths of the full query data range. The lighter-shaded right-hand depth column displays the depth range currently displayed. The depth navigation bar can be scrolled to zoom in or out, dragged up or down the full depth rage of the query, or expanded and contracted using the triangular "handle" areas. Scrolling using the mouse wheel on a data panel will also zoom the depth selected with the depth navigation bar.

Lower Image:

the depth control is "zoomed in" to view from 4 m to about 35 m depth.

Recovery Panel

The recovery panel is shown in Figure 7. The panel is divided into four column areas:

1. Interval cored: shows the full interval cored (or drilled) and the core or drilled interval number
2. Interval recovered: length recovered for that core, along with core type
3. Section: number and length of sections taken from that core
4. Whole-round samples taken from specific sections

Mouse Zoom and Position Control

The mouse wheel can be used to zoom the data display in and out; all panels scale at the same rate. The mouse can also be used to "grab" and move the display up and down the hole within the bounds of the original query. Note that because of screen refreshes with mouse movement, using the mouse controls may result in program lag.

Unzoom

Clicking Unzoom on the

Title Bar returns the display to the full scale of the original data query. It will not zoom out to the entire hole unless that is what was queried. This feature allows the user to zoom in within queried data and zoom back out to full results without having to run a new database query; this speeds up operations significantly.

Section and Whole-Round Sample Breaks

The checkboxes Sect break and WR break on the title bar display horizontal lines across all data panels where section breaks occur or where whole-round samples (e.g., interstitial water or microbiology samples) were taken, respectively. Either or both checkboxes may be selected.

Panel View Options

Data panels have scale bars on either the top or bottom or both horizontal axes. Components plotted against the top axis are shown in the header of the panel; those plotted against the bottom axis are shown in the panel footer.
The panel options window for each axis provides the capability to alter data and sample properties (Figure

9). Changes are shown in the panel immediately; Exit closes the window.

Image Modified

Figure

9. Panel options for top axis.

Panel Scale

The panel axis scale limits can be set to autoscale to the range of data retrieved (+5% to keep the data points from the edge) or set to a specific numerical range (e.g., 0–100 for L*, which by definition cannot be <0 or >100). The default axis scaling can be overridden by clicking in the header (for top axis) or footer (for bottom axis) to open the panel options window. It is recommended to position this window away from the data panel being adjusted so that changes can be seen before clicking Exit.
Any numerical value can be entered into the minimum and/or maximum fields, then click Apply scale change. The change in scale will be immediately visible on the selected panel.

Data Property

For data panels, the user may choose to display or hide connecting lines, symbols, and/or text. If multiple data sets are displayed on the same axis, as shown in Figure

9, the user may switch between the color-coded data sets (in this case, blue for b* data and green for GRA density) in the drop-down selector to change the line, symbol, and/or text options independently for each type of data. Note that only track data will display lines. Discrete sample data displays only as symbols or text.
*Figure

9. Panel options for top axis.*Changes are shown instantly in the data panel. To cancel a change, simply uncheck the property selected.

Sample Display

If the panel to be changed is a sample panel, the Sample display options will enable, allowing the user to toggle area shading (fill area) or display text (display text button).

Advanced User Options

Users with appropriate privileges may log in to access the Panel Builder and Template Builder.
Panels can display data sets that may be analytical data, sample information, images, and/or lithology. Data types can be combined in a single panel if desired.
Templates are made up of several panels that plot side by side on the main results screen after the LIMS query. Related data sets can be viewed simultaneously for comparison or trend recognition, or several types of data can be viewed together as an overview for quality control.
Note: The Panel Builder and Template Builder windows appear in new tabs in the browser. If the user logs out of LIVE on the main screen, or closes its tab, the Panel Builder and Template Builder windows will be orphaned. They will appear to be functional, but will not allow the user to take any action.
Note: If the user plans to make a lot of panel and template changes, a good technique is to open LIVE in two different browsers (e.g., Firefox and Chrome), make and save changes on one, and observe the changes on the other. This prevents the user from having to log in repeatedly after refreshing the browser in order to access new templates, if any.

Panel Builder

Click Panel Builder on the main screen to open a new tab for the Panel Builder. The entry screen shows version information, login account, and a list of panels with two controls: New and Select panel (Figure

10).

10. Panel selector.

After selecting an existing panel to edit or modify, change the panel name to ensure that panels already used in active templates remain as originally designed. Changing or deleting a panel in use in active templates may cause problems for other users

. Proceed with care; DO NOT give a panel the same name as an existing panel.

Panel naming convention is optional but may reduce panel duplication: include at least component plotted + analysis code (if needed) + axis + instrument (if needed) + other information (if needed). Examples:

MS_WRMSL_top_MSPOINT_SHMSL_bottom           RSC_AB_top_L_bottom          SRANL_HI_top_OI_bottom           PWB_yz_manual_top

The panel shown will plot the principal lithology component as a colored area block. In the following example tThe lithology is picked up from the Sediment tab in the 362_-macro DescLogik DESCLogik template. The label "Principal lithology" will appear on the bottom axis of the panel.
Important! This panel will only work for a specific expedition DESClogik template, and DESClogik tab

. It must be changed before it will function for a different DESClogik template or tab.

Editing an Existing Panel

Warning! Changing or deleting a panel in use in active templates may cause problems for other users! Proceed with care.

Highlight a panel from the panel list on the Panel Builder main page and click Select Panel. The builder screen will populate with defined parameters for the selected panel (Figure

16). The name can be changed, data elements added or removed, default panel width changed, and min/max top and bottom axis scales set or (if left blank) set to autoscale.

Important: Rename the panel to avoid conflict with this existing panel being used in active templates.
This panel shows caliper P-wave velocities in the x, y, and z directions, both manual pick and autopicked, all on a single plot. Autopicked and manual pick x-direction measurements are shown on the top axis, and autopicked and manual pick y- and z-direction measurements are shown on the bottom axis. The data values will be shown as symbols, as they are discrete measurements, and top and bottom axis scales will automatically set to fit the data values in the sets plotted on each axis. As these components all share the same unit, they will be directly comparable plotted on the same axes.

Template naming conventions

Include enough information so users can tell what is in the template, for example:
LSIMG_COUL_RGB_RSC-L      MS_MSP     GRA_MAD     PWL_PWB_PWC (or maybe PWAVE_ALL) 349_LITH_WRND-GRA_NGR_RSC

Alternatively, templates used for routine QA/QC can be named for their function, for example:
BOX TIME     LITHOLOGY 362     READY TO SPLIT     WHOLE-ROUND DATA     MICRO IMAGES ALL

Editing an Existing Template

An existing template can be modified and saved as a new template. Warning: rename the modified template before saving! The existing template below (Figure 19) was built as a quality control check on whole-round data. The panels in the template are listed (note the panel names are not exactly like they were named in the Panel Builder, as the application adds additional information to the panel name. The five panels in this template include (1) magnetic susceptibility from WRMSL and STMSL, both plotted on the same axis (top), (2) GRA density from WRMSL and STMSL, both plotted on the same axis (top), PWL (by default, x- and y-directions only, (4) NGR plotted on the top axis, and (5) thermal conductivity plotted on the top axis. Note that both the panel names and the template names are clear enough to determine what they contain.

If we wanted to add the section-half image to this template, we would select Data group I_depth_referenced, select the panel that shows the cropped jpeg or tiff, and click Add panel. If we wanted the image to be the first panel shown, we would use the up arrow to move the image panel to the top of the list. Very important – we would rename the template something descriptive such as Whole-Round Data plus LSIMG.
