Fix bug in PC feature channel selection #42

Closed jsiegle closed 5 years ago

jsiegle commented 5 years ago

For the outputs of Kilosort2, the channels of the PC features matrix are not ordered consecutively. This violates an assumption of the calculate_pc_metrics function in the quality_metrics module. The symptom is that the PC-based metrics cannot be computed for a subset of units, because the PCs for the unit of interest get excluded from the calculation.

This should be fixed by commit 6cd72ff. I'm going to leave this open until we've had more time to test it.
