I have a continuous physiological measure (raw_data), 60 measurements/sec,
taken during scanning with a TR=2.
It seems to me that I should convolve the raw_data with hrf prior to binning
in 2sec bins.
I have noted the following procedure in other posts:
hrf=spm_hrf(TR)
convraw=conv(raw_data, hrf);
convraw=convraw(1:length(raw_data));
Is this the correct method for this data? Should the temporal resolution of
the hrf be closer to the temporal resolution of the raw_data?
THanks for any suggestions.
