Create a function to write out continuous physiological recordings physio.ons_secs.[t,c,r,svolpulse] according to BIDS in a function, e.g., code/readin/tapas_physio_write_physlogfiles_BIDS.m
This function should be called within tapas_physio_main_create_regressors either after syncing (labeled part 2 of the file) or preprocessing (part 3 of the file would be a BIDS derivative, but maybe more useful?)
@mrikasper where can I find the sampling frequency? Is it physio.log_files.sampling_interval? Also I am committing into the branch created from the issue, if you want to have a look
Related to this common user request, it would be great to also allow for the extraction of derived physiological measures (RVT, HRV) at the initial sampling frequency
At the moment, this is only possible after the resampling to the volume onsets of the fMRI time series
The output should ultimately be BIDS, but a first step would be to provide the traces themselves at raw resolution in the physio.mat file
