There are some features in the search results page, and/or the collections page that are broken — these are:

Go to https://genenetwork.org
Select "Mouse (Mus musculus, mm10) for "Species"
Select "BXD Family" for "Group"
Select "Traits and Cofactors" for "Type"
Select "BXD Published Phenotypes" for "Dataset"
Type "locomotion" in the "Get Any" field (without the quotes)
Click "Search"
In the results page, select the traits with the following "Record" values: "BXD_10050", "BXD_10051", "BXD_10088", "BXD_10091", "BXD_10092", "BXD_10455", "BXD_10569", "BXD_10570", "BXD_11316", "BXD_11317"
Click the "Add" button and add them to a new collection
In the resulting collections page, click the button for any of the listed failing features above

The "CTL" and "WCGNA" features have a failure mode that might have been caused by recent changes making use of AJAX calls, rather than submitting the form manually.
The "MultiMap" and "Generate Heatmap" features raise exceptions that need to be investigated and resolved
The "Partial Correlations" feature seems to run forever

We break-out the issues above into separate pages to track the progress of the fixes for each feature separately.
