Saved Sorter Object has no information about the mapping from units to channels #1952

Closed Sudhanshu-Sb2002 closed 1 year ago

Sudhanshu-Sb2002 commented 1 year ago

The entire spikesorter output (the .npz file and other files exported) doesn't have any information about which electrode/channels the unit belongs to. What is the use of unit-ids if I don't know which channels they came from?

Unit ids are the IDs that a sorter assigns to each unit. Toe Sorting ibject itself doesn't know the channels a unit was found on, even because many times it's multiple channels.

To combine the information of a spike sorter output with the recording you should exrtact_waveforms and use the WaveformExtractor.
