RE: spm_fnirs_read_nirscout.m issue
Dear Don,
Thank you for sharing your code.
Yes. As you mentioned, spm_fnirs_read_nirscout.m reads information about channel configuration from header file (*.hdr), and writes that information as 'ch_config.txt' file. I think that your code skips this routine and prevents ch_config.txt file overwritten if 'ch_config.txt' file already exists in a directory of the header file (*.hdr).
Best wishes,
Sungho
PS: If channel configuration is changed or does not match with information in the header file (*.hdr), you can also save it as a file with different name (eg, re_ch_config.txt), and use that file as input for spatial preprocessing.

Hi Sungho,
I was running into some problems with some code I'd written that deleted channels in our nirx datasets and wrote out new channel configurations files. I hadn't realized until late that the spm_fnirs_read_nirscout script was overwriting my channel configuration file between lines 150-154. I modified the file as follows to test for an existing file, so as not to overwrite the customized one I had produced:
sfname = fullfile(pathstr, 'ch_config.txt');
if ~exist(sfname, 'file')
fid_w = fopen(sfname, 'w');
fprintf(fid_w, '%s\r\n', 'Ch, Source, Detector');
for j = 1:P.nch, fprintf(fid_w, '%s\r\n', [num2str(j) ', ' num2str(ch_sd(j,1)) ', ' num2str(ch_sd(j,2))]); end
fclose(fid_w);
end
I attached the revised file for your convenience if it makes sense to you. At any rate, the modification works well for me.
Best,
Don
