+
+### Describe the bug
+
+When calcuating principal components from a correlation matrix, attempting to add one or more PCs to the collection returns the following error:
+
+```

+       ValueError: not enough values to unpack (expected 2, got 1)
+
+```
+
+### To Reproduce
+
+* Add transcript traits to a collection.
+* Calculate the correlation matrix.
+* Select One or more principal components.
+* Click 'Add' to add this to the collection.
+NOTE: This was done with the 'BXD Aged hippocampus individual data' dataset (GN712).
+
+### Expected behavior
+The PC should be treated as a normal trait and added to the collection.
