By default, KiloSort removes "bad" channels that have low spike rates; it could be that a majority of your channels don't have spikes, so are not considered. If this is indeed the problem, you can force it to use all channels by setting ops.minfr_goodchannels to zero. (or the analogous field in the GUI, it's default is .1)

Thank you!

You might also want to make sure your channel map has the correct number of channels, if it is importing fewer into the GUI by default (in the GUI, you should see all 270 channels in the probe layout window, and bad ones will be marked yellow or red, so if the automatic channel exclusion is removing 200 of your channels, you should see about 200 yellow/red channels, and 70 green ones)

I made an issue to remind myself to make this more clear in the GUI: #20
@barbouni if this thread has answered your question, go ahead and close this issue? Thanks -
