¥ -stim_maxlag
k p = option to set the maximum lag to p for stimulus
timing file #k for k=0,1,2,É
H Stimulus
timing file input using command line option -stim_file k
filename as before
H Can also
use -stim_minlag
k m option to set the minimum lag if you want a value m different from 0
H In which
case there are p-m+1 parameters in
this HRF
¥ -stim_nptr k
r = option to specify that there are r stimulus
subintervals per TR, rather than just 1
H This
feature can be used to get a finer grained HRF, at the cost of adding more parameters that need to be estimated
¥ Need to make sure that the input
stimulus timing file (from -stim_file) has r entries per TR
¥TR for -stim_file and for output HRF is data TR ü r
