BUG: PCA features zero values on relevant channels #782

Closed ckwalters closed 2 months ago

ckwalters commented 2 months ago

Describe the issue:

Hello, I often see PCA feature values of zero when curating KS4 results in Phy on channels that are on the edge of the template (but for my large amplitude units, relevant to sorting). Is there a setting for increasing the number of channels on which features are actually calculated, or is this unintended behavior? Thanks!

settings['nearest_chans'] controls the number of channels used, which is 10 by default.
