D128 Probe Channel Map - Githubissues

Hi everyone,

I am recording with a 128 channel probe using OpenEphys data acquisition system. Below is a MATLAB code that shows how I'm trying to create my channel map. When I don't include bad channels, spike sorting runs but I get a weird drift estimation. When I include the bad channels, I get the following error. I added an excel sheet that shows the specifications of the probe. Yellow labeled channels are bad ones. I would appreciate if you can tell me what I'm doing wrong and help me create the correct ChanMap.

chanMap = [65,64,66,63,67,62,68,61,69,60,70,59,71,58,72,57,73,56,74,55,75,54,76,53,...

chanMap0ind = chanMap - 1;

Bad_Channels = [1 3 5 7 9 11 13 32 47 48 49 51 65 66 67 69 71 73 81 83 85 87 89 91 93 99 111];

connected = true(128, 1); connected(Bad_Channels) = 0;

xcoords = 15 * repmat([1 0], 1, 64); xcoords(Bad_Channels) = NaN;
ycoords = -15 * [1:128]; ycoords(Bad_Channels) = NaN;

kcoords = ones(1, 128); kcoords(Bad_Channels) = NaN;

fs = 30000; 

save(fullfile(fpath, 'chanMap.mat'), 'chanMap', 'connected', 'xcoords', 'ycoords', 'kcoords', 'chanMap0ind', 'fs')
