Once you have a folder containing one or more sample types, you can view and manage them at several levels. This topic describes what you will find at each level.

View All Sample Types

You can add the Sample Types web part to any folder that has the Experiment module enabled. This web part lists all of the sample types available in the current folder. Note the "Sample Count" field, which is a reserved, calculated column that shows the number of samples currently in a given sample type.

You can see this example in LabKey's proteomics demo.

View an Individual Sample Type

Clicking on the name of any sample type brings you to the individual view of it's and its properties (metadata). For example, clicking on the Yeast Samples in the web part shown above brings you here:

Options on this page:

  • Edit Type: Add or modify the properties and metadata fields associated with this sample type. See Create Sample Type.
  • Delete Type: Delete the sample type. You will be asked to confirm the deletion.
  • Import More Samples: See Import Samples.
You can also hover over any row to reveal (edit) and (details) icons.

Delete Samples

To delete one or more samples, check the box for each of the desired row(s) and click the (Delete) icon. You will be asked to confirm the deletion and reminded that deletion cannot be undone.

It's important to note that samples cannot be deleted if they have derived sample or assay data dependencies.

  • If all rows selected for deletion have dependencies, the deletion will be denied.
  • If some rows have dependencies, a popup will explain that only the subset without dependencies can be deleted and you will have to confirm if you still want to delete them.

View an Individual Sample

Clicking on the name of any sample in the sample type brings you to a detailed view of the sample.

The Sample Type Contents page shows you:

  • Standard properties. These are properties defined for a group of samples at the sample-type level.
  • Custom properties. These are properties of this individual sample.
  • Lineage. This section details the Parent Data, Precursor Samples, Child Data, and Child Samples.
  • Runs using this material or derived material. All listed runs use this sample as an input.
It also provides links to:
  • Edit the properties of the sample.
  • Derive samples from this sample. This is covered in the next topic.
