RE: setup error
Dear Diksha,
Your last onset time is at 317.51seconds. Since you removed the first 4 scans, your functional series is 312 seconds long (156 scans, 2 second tr), hence the error message (onsets extend beyond the end of the scanning session, i.e. 317.51>312). You simply need to subtract 8 from all of your onset times in order to account for the 4 removed scans.
Hope this helps
Alfonso

Dear Alfsono ,
thank you making response
i have got data through online website . and for each condition in every subject there is given infromation onsets
and given TR time is 2 sec total volumes are 160 . at preprocessing time i have deleted first four volumes and simply put given onsets(without any change) at each condition.
so is it correct way or it needs some corrections
please find attached on sets text files .
awaiting to hear you back.
thank you in advance
