about calculation of theta-sequence #240

Hi, @DavidTingley

I'm recently using your decoding code. There's two "fields" in some of the structure variables, which I don't really understand.

one is "spike.spindice", I wonder if spikes.spindices(:,1) is the timestamps of spikes and spikes.spindices(:,2) is the cellID of corresponding spikes?

the other one is : fields{behavior.events.trialConditions(t)}{cellIDs(cell)}{1}.COM What is this?

Best, LU

DavidTingley commented 6 years ago

@dlevenstein for spindice description the .COM field is the center of mass of the place field. It is a weighted mean of the bins within the field start/stop

Yup, spikes.spindices(:,1) is the timestamps of spikes and spikes.spindices(:,2) is the cellID of the corresponding spikes.

the information is redundant with spikes.times, but is in a form that is useful for some operations/plotting/etc.

Thank you so much guys. @DavidTingley @dlevenstein
