Introduction
This guide covers 16 of the most commonly asked questions by description and paleontology scientists about DESClogik. The guide is intended to assist technicians and scientists when the Description technician is unavailable.
1. I can't login to DESClogik.
If a scientist can't log into DESClogik, it could be two things. Either they have changed their e-mail password, but not their LIMS password; or, they have not been assigned privileges to DESClogik. To change their LIMS password: go to the ship website, Access LIMS Applications, then click Change password (second from the top; http://web.ship.iodp.tamu.edu/ChangePassword). Enter your information and it should change instantly. If their password is correct, and they still can't access DESClogik, they may not have privileges. See the Curator as they are responsible for setting privileges.
2. Which template do I use?
- Templates are typically named at an expedition level. Select your expedition from the group drop-down (Figure 1).
- Templates can be divided into two groups: core description and paleontology
- Core description uses two templates: macroscopic and microscopic
- Macroscopic templates correspond to section half, core, and hole descriptions. This is the primary description workbook for core describers.
- Microscopic templates correspond to smear slides and thin section descriptions.
- Paleontologists use paleo templates which are broken up by specialty: Nannofossil, Foraminifera, Diatom, Radiolaria, ect. Choose the template which corresponds to your discipline.
To select a template click on the big "T" at the top left of the main screen in the Spreadsheet Tools tab and choose . Choose from the templates listed by group (expeditionin your expedition (Figure 1). Double click the one you 're looking forwant to work on. All other expeditions should not be visible to the scientist; if they are, notify DESC Tech (admin). This screen is shown in Figure 1 below.

3. I am a paleontologist, how do I enter my samples?
Paleontologists Scientists are responsible for entering paleo and smear slide (SS) describers are responsible for creating their own samples using samples in Sample Master. In general, paleo samples are For most paleo samples, these will be taken off of the PAL whole round. Paleo samples are then children of the PAL whole round with the test being their respective paleontological sub-discipline. SS Smear slide samples will be children of either the archive or working section-halves, and are designated by the test "ss". Two separate quick guides have been created for entering paleo and smear slide samples into Sample Master. These are usually furnished given to the scientists before our first core. These guides are located in on Confluence and within the following folder on VOL1: V:\IODP_Share\ALL things DESClogik\Technician Guides and Quick Starts.
There are several other guides and resources in that folder which help with common entry mistakes, printing labels and general tips. Any of these guides can be given directly to the scientists.
4. How do I find my samples in DESClogik?
DESClogik has a To enter data or to download existing data, you need to use the sample selection (and corresponding filter feature, which ) in DESClogik. This is the only way scientists can to enter or view data . Scientists click on the blue globe, select expedition -> site -> hole, check the boxes to apply the various filters, and then double-click on the sample populated into the Samples list. Examples are shown in the figures below. For more details on possible sample types, see the PAL Sample Entry guide mentioned in question 3.
Users MUST have a sample type (left column of the sample selection window) selected, or no samples will show up in the sample selection. The column on the right (test lists) is only used to further filter sample types after they have been selected in the left columns.
Core describers typically select Section halves and Show only… -> Archive halves, Figure 2.
Paleontologists typically select TPCK or OTHR under Sample types, and by discipline under Test list, Figure 3.
Smear Slide (SS) describers select Smear slides under Sample types, and Thin sections for thin sections.
Figure 2. Sample Selection. Shown here is the section half selection for core description.Paleontologists will have to filter by their Sample types and by (Figure 2). The "select sample" icon is directly connected to samples available within Sample Master.
- Click on the "Select Sample" icon (Blue globe)
- Select Expedition > Site > Hole
- Check the appropriate filters corresponding to your sample
- For Macroscopic descriptions: these filters typically are "Section halves" and Show only "Archive halves" (Figure 2)
- For Microscopic descriptions: these filters are "Smear slides" or "Thin sections" (Figure 2)
- For Paleontologists: these filters are "TPCK" or "OTHR" under Sample types, and then by discipline (DIAT, NANNO, ect) under Test List (Figure 3).
Users MUST have a sample type (left column of the sample selection window) selected, or no samples will show up in the sample selection. The column on the right (test lists) is only used to further filter sample types.
NOTE: Paleontologists have to filter by Sample types and Test list, so, which boxes to check depend on how they have entered their sample . The most common into Sample Master. Common sample types are TPCK for nannofossils, diatoms and radiolarians, and OTHER for foraminifera (forams). Note: ignore Ignore test list types FORAMB and FORAMP. You can always check more boxes, but then you could be entering For pale samples, careful that you do not enter paleo data on chemistry samples. The test Test filters are pretty straightforward as long as samples were created with the correct test. A paleo sample example is shown in Figure 3 below.

5. How do I upload data, and how do I know it's been uploaded?
...
- To Upload data: Click the "Upload" icon (Figure 4).
- Data which has not been uploaded to our database are highlighted in blue
- Data which has been successfully uploaded will change from blue to white.
- To check your data. Download the samples (which you have just uploaded) from the database.
- To Download data: select the set of samples you'd wish to see (using the Select Sample icon), then click the "Download" icon.

6. How do I download my data/Why can't I download my data?
- To
...
- Download data
...
- : the preferred method is to
...
- download by "Hole". To do this, select "Hole" from sample types within the "Select Sample" icon. Click the "Download" icon. Downloading by hole will give you all the data for that template
...
- and for that hole.
...
- Alternatively, the user can select a set of samples
...
- by
...
- highlighting samples from the Sample list window shown
...
- within the "Select Sample" icon. This method is preferred if there is a large amount of data.
If they you do not see their your data upon download, first try and download by Hole. This will catch all sample types entered as well as all depths. There is a good chance they logged their data against Potential mistakes are that data has been assigned to the wrong sample , or the that depths in the hole have shifted and a need to be re-calculate depths must be done in Sample Master. It is also possible they did not upload anything last time they entered, or someone may have canceled their data. The DESC tech can find a recovered copy of their screen last time they uploaded. See question 12. DESClogik froze while uploading data, what do I do and how can I recover my data?
7. How do I delete (cancel) data?
Deleting and canceling in DESClogik mean two different things. "Deleting" means clearing a cell or row of cells of un-uploaded data. "Canceling" means canceling in the database, and it is not easily recoverable. To delete data in a single cell use the delete key. To delete an entire row, right click on the row number and select clear row. A warning will appear. To delete un-uploaded entries from either the whole sheet or the entire template, click the Clear icon that's to the right of the Download icon, with or without the All Tabs box checked.
To cancel the data, select the cell and hit the Delete key or right-click a cell and select Cancel Value. You can highlight multiple cells and hit the Delete key. A warning will appear asking if you really want to cancel all the cells' datacalculated in Sample Master. It is also possible that data was not uploaded, or it has been cancelled. If this is the case see a DESC tech.
Note: Deleting and canceling in DESClogik mean two different things.
- Deleting means clearing un-uploaded data.
- Canceling means deleting downloaded data. Deleting downloaded data means that you are erasing these values from the database. Canceling values is very hard to un-do, and should only be done by qualified users.
- To delete data in a single cell: use the delete key.
- To delete an entire row: right click on the row number and select clear row. A warning will appear.
- To delete data from the whole sheet or whole template, click the Clear icon.
8. How do I export an Excel copy of my data?
Exporting an Excel copy is very easy. Download all relevant sample data (see Question 6). Click the green Export icon at the top right of the window icons, Figure 5. Check the box Data only and hit O.K.; the Include classifications box is automatically checked and should be. This will export an Excel workbook with everything downloaded, if you do not check this box you will get a blank Excel workbook with only the column header names. Sometimes these are useful if scientists (usually structural geologists) wish to record by hand their observations and measurements on paper first. However, this is typically discouraged because it's double the work and prone to entry mistakes.
To download and export all the data on every tab of the DESClogik template, simply check the All Tabs box before downloading, and leave it checked when exporting (Figure 5). NOTE, the export progress window will often hang after it finishes, you can just close the window with the red "x" in the corner and all will be well.

9. How do I import data to my template?
Importing data from Excel can be a bit tricky due to a few DESClogik quirks (you would probably call them bugs). In general you simply copy and paste in from an Excel sheet, being sure that the columns are all the same, and the samples are correctly labeled. The trick is to not copy the depths (the offsets are okay). DESClogik will calculate the depths for the user once the samples, with the intervals, are pasted in. So copy and paste in two chunks. Note: it is really easy to mess up which data goes with which sample, especially since the cell you click to paste in will populate with whatever sample is loaded from the Select Sample globe. This sample will be overwritten, so no worries there. Lastly, hit Upload.
10. How do I move, widen, or remove columns/Can I change the look of my template?
Scientists have a few options when it comes to customizing their templates. They can widen and shrink columns just like in Excel. They can hide and unhide columns as well by right clicking, choosing Edit Visibility, checking and unchecking the list of all columns. Data associated columns will not disappear, the column will just have to be unhidden in order to download data. These permissions are set by the DESC administrator, so some features may not be available. Changes can be saved permanently or per session; a dialogue warning will appear after each action (Figure 6).
NOTE: changes saved will apply to all users of the template, and some might not like what one person has done.

11. My data looks different then when I uploaded it/there are duplicate descriptions?
If downloaded data does not look the same as when uploaded, the template column definitions might be duplicated. The administrator must correct the issue, so please let them know.
If there are duplicate descriptions, it is likely the scientists have not been downloading the data for their samples before entering. To correctly edit or add data to a described sample the user must first download the data (see question 6). Then they can enter new data or use the delete key to cancel and or edit existing information. It is just good practice to download before entering. The duplicates can be removed by converging data to one of the samples, and then canceling the others. This is best left to the DESC admin.
12. DESClogik froze while uploading data, what do I do and how can I recover my data?
A good practice reminder is to have the user export an Excel copy (see question 8) before making any large uploads, i.e. a core's worth. Then the user knows for sure the data is saved with them and they can copy and paste it back in (question 9). If they have not exported a copy, only a DESC administrator will be able to recover a snap shot of the DESC entry form at the time of upload.
If DESC is totally frozen, then the program must be killed within the Windows Task Manager (Ctrl+Alt+Delete). After killing the program, reopen DESC and have the same user who was logged on at the time of the freeze log in again. The Autosaves upon upload is specific to each user, so if the user from a previous shift was still logged in, recovery would have to wait until they return (or you could try and guess their LIMS password!). For this reason, users are encouraged to log out at the end of their shifts and let the new shift log in. Once logged in, open the proper template, go to the Recovery tab, click on the Last Autosave, and have an admin log in (Figure 7).
Figure 7. Recovery and Admin Login Screen.
Now the admin can browse autosaved files by timestamp. The last save is on the bottom of the list. Make sure the entry screen is clear and select the appropriate file, and click Load. The program will populate the template with all the entries at the time of autosave, Figure 8. These entries will have to be uploaded to save them to the database, so click back onto the Spreadsheet Tools tab. It's not perfect, and some entries might not be there. The user needs to check what's there and upload when they are satisfied--just hit the Upload icon at the top of the window (Question 5.)

13. DESClogik gives a warning message when I try to exit/clear samples?
If a warning message appears when exiting DESC, or when clearing samples, like the one in Figure 9, then the user has entries/data they have not yet uploaded. Each template tab with un-uploaded data will have an asterisk next to its name. The warning message gives the user the option of losing the changes and closing, uploading before closing, or canceling. It is best practice to cancel and look for the un-uploaded data and clear it or upload manually before closing. This should prevent unwanted removal of "good" description data.

14. Do I need to describe the missing whole-round samples, like PALs and IWs, in DESC?
NO. When the publications specialist plots their visual core description sheets (VCDs/Barrel Sheets) the software they use will fill in the missing core with an appropriate sample symbol. Describers should be reminded to only describe what they can see, and enter only data that would be considered an observation, not an interpretation. They do need to add a foam spacer to the bottom of the section-halves before they scan with the SHIL. They do not need to insert foam on the SHMSL.
15. Where are hand lenses, scrapers, smear slide sheets, etc.…?
Hand lenses are supposed to be in the blue cabinets (3rd drawer down) past the description tables, under the smear slide station. Numerous other description related things are in that drawer/cabinet, like protractors, goniometers (fancy protractor), grainsize cards, microscope slide, paper description sheets, toothpicks, etc. If none are there, try the Special Curation Tools drawer of the splitting room. Lastly, you can get a new one from the ALO office; ALO needs to checkout.
Stainless steel core scrapers are in the Special Curation Tools drawer of the splitting room. You might also find hand lenses in there.
There are often leftover smear slide (SS) description sheets in the Description drawer, but it is best to look in the VOL1 folder link below and under the DESClogik_EXP# folder. The science party makes changes to these from expedition to expedition, so old ones might not match. You can always copy a blank one if they asked you in time.

16. I need to add a term to our value lists.
Terms can only be added by a description technician (admin). You should have the scientist send all changes in an e-mail to the DESC tech, with their fellow description scientists copied on that e-mail.
In the meantime, scientists can type the value into DESClogik descriptions, and the DESC tech can add the value to the value list after the fact.
