Hello!
Is it possible to display cluster features in global PCA space in Phy?
I am using silicon probes that have recording sites on both sides, and there is some double counting of spikes between clusters across the two sides of the shank (see attached pic) - spikes of a blue unit on one side of the shank also appear as part of a red unit on the other side.
I would like to put these clusters into a common PC space to see the cluster overlap, and perhaps see if I can cut out the double counted spikes.
I have figured out how to resolve this prior to a call to Kilosort by grouping channels on the two sides of a shank (rather than treating these as independent groups, as is apparent in the image). However, I have many manually curated sessions in which this problem appears, so I wonder if there's a way to redefine the PC space after automated clustering has taken place.

Thank you for any advice!
