Questions about bz_LFPfromDAT

[farazmoradi]

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)))) Brendon Watson, MD-PhD Assistant Professor in Psychiatry, Bioinformatics and Biomedical Engineering Biomedical Sciences Research Building, Room 5059 University of Michigan 109 Zina Pitcher Place Ann Arbor, MI 48109-5720 Lab Website: http://watsonneurolab.org Clinical phone: 734-764-0231
