AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi,

I have the following task (imagination experiment): Task and rest blocks had a duration of 30 s and were played out in the following order: rest, task, rest, task, rest, task, rest, totaling 105 repetitions. There were 2s between each scan.

From what I understand i should use @make_stim_file.

@make_stim_file -outfile imagination_out

headers -> imag
'imag' -> 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
3

How do I get the zeros for the last rest phase? Is there an easier way to write 16:30? Finally, I presume that the time between scans (2s) will be used to calculate the HRF. Where is this done? In 3Ddeconvolve (processed by afni_proc.py)? How is it put in as an input?

Many thanks,
Ranjan
