I’m trying to handle a situation whereby two of my participants are missing 1 run each of their fMRI data. There should be a total of 6 runs, but these two people have only 5 runs. In each case, I do still have the behavioural stim_time files and responses. Should I (a) mark the missing row in the stim_time files as ‘no responses’ by writing “* *”, or should I (b) leave the row out entirely since afni_proc will only pick up on 5 runs and therefore look for 5 rows in the stim_time file?
Thanks in advance!
