Questions about bz_LFPfromDAT #421

Open farazmoradi opened 11 months ago

farazmoradi commented 11 months ago

Hi,

I wanted to know how the filtering and downsampling is applied on the DAT file using bz_LFPfromDAT function. I tried to check the code and I realized the sinc_filter function was used for filtering, but I couldn't understand how the downsampling was applied.

Thanks

Looks like it simply takes one out of n samples using something like this gather_try(int16(real( tmp(sampleRatio:sampleRatio:end-ntbuff))))
