This topic covers the management of samples and types of samples within the Sample Manager application.
Freezer Management Available

You can track the storage and usage of samples through the Freezer Management feature. Learn about storing samples in freezers here:

View All Sample Types

To view all the Sample Types defined in LabKey Sample Manager, click Sample Types on the main menu.

You can select between several ways to view all the samples in the system.

Grid

The grid view of all Sample Types lists the name, description, and other details about each type of sample in the system. You can also download a template for easier import of data from files.

Click the name to open the set of individual samples of that type.

Heatmap

The heatmap shows a 12 box row for each type, representing 12 months of sample collection. Darker shades are used for months where more samples were collected. Hover over any square for more details.

Click a square to open a grid view of data filtered for that month and Sample Type.

Cards

The card view of all samples indicates the total number of samples for that type.

Click a card to see the grid of data for that Sample Type.

View Samples of One Type

You can open the grid of all samples of a specific type in several ways:

Sample Type Details are shown in the left hand panel, including the Description, Naming Pattern, Metric Unit, Parent Import Alias(es), and Source Import Alias(es). The right hand panel shows sample type insights

Below the details and insights, the grid of Samples offers menus, filtering, sorting and searching. Learn more in this topic:

Sample Type Insights

The panel of Insights gives a quick visual summary of Storage Status, Sample Status, and Aliquots. Color coded bars show the relative prevalence of each state. Hover for details, shown here, how many samples are checked out. Click any bar segment to filter the samples grid to show only those samples.

When several sample Status values have the same base type, such as "Received" and "Available" both being "Available" samples, you can hover over portions of the bar for details of that specific sample status. Click any bar segment to filter the samples grid to show only those samples.

Menu

The menu in the upper right offers these options:

  • Edit Sample Type Design: Reopen the existing details and fields; edit using the same interface as you used to create the Sample Type.
  • Delete Sample Type: Note this will delete all sample data as well
  • View Audit History: Administrators can view the audit history for this Sample Type from this link.

View Individual Sample Details

Click the Sample ID for any sample to view the details entered about it. Panels for Storage Location, Aliquots, and Details give you the specifics for this sample. From the menu you can create new samples of any type, delete this sample, add it to a picklist, or upload assay data for this sample. Storage editors can check it out or discard it. You can also view the audit history for this specific sample.

Panels on the Overview tab include:

  • Storage Location: Shows the current location, checkout status, and storage details.
  • Aliquots: Details about any aliquots created of this sample.
  • Details: Details about this sample.
    • For an aliquot, this panel will include details about the aliquot and about the original sample.
  • Source Details: Information about sources of this sample.
  • Parent Details: Information about parents of this sample.
The tabs along the top of the details page let you see the following for this specific sample:
  • Lineage: View a lineage graph or grid.
  • Aliquots: See aliquots and subaliquots of this sample.
  • Assays: All assay data available for this sample (and any aliquots).
  • Jobs: Find all jobs involving this sample (and any aliquots).
  • Timeline: See a detailed timeline of all events involving this sample.

Edit Sample Details

To edit the details for this sample, including the description, click the (Edit) icon for that section. Make changes using dropdowns and selectors similar to when you originally assigned the values. Remember to click to Save your changes.

Edit Sample Lineage

You can edit the source and parent information (i.e. the lineage) for a sample directly from the sample details page. Use the (Edit) icon for the Source Details or Parent Details section as needed. Make changes using dropdowns and selectors similar to when you originally assigned the values. Remember to click to Save your changes.

Delete Samples

Deletion of samples may be necessary for a variety of reasons, and once completed, deletion cannot be undone. You can delete a single sample while viewing it's details page.

  • From the detail page for the sample to delete, open the menu on the right.
  • Select Delete Sample.
  • You will be asked to confirm the deletion.

You can also delete one or more samples from the grid view for the Sample Type. Note that you can only delete up to 10,000 samples at one time, so if you need to delete more than that, perform the deletion in batches.

  • From the grid view for the type of sample to delete, select one or more checkboxes for the sample(s) you wish to delete. To select all samples, use the checkbox at the top of the column.
  • Select Edit > Delete.
  • You will be asked to confirm the deletion.

If any of the samples you attempt to delete were used to derive other samples (i.e. are parent samples) or are associated with assay runs (i.e. linked as lookups from data you have imported) you will not be able to delete them. The popup will give you more details and ask you to confirm or cancel the partial deletion of any samples without dependencies.

When you delete samples, they will be automatically removed from any picklists to which they had been added. On affected picklists, users will see a blank row where the deleted sample used to be.
