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, all

We have a design which is a bit troublesome in editing the 1d file for analysis.

It's a block design and the TR is 3.6s. For each block, condition A is presented for 4320ms followed by 180ms fixation, this repeats four times, which means a block lasts for 18000 ms in total, corresponding to 5 TRs.

As the duration of stimulus is not the multiple of TR, I wish to use -stim_nptr option. This is my first time that I use -stim_nptr option, so here I post my settings and the arrangment of 1d for one block. Please have a look at this 1d and let me know whether they are applicable to my design.

-stim_nptr 1 4

1d for one block, 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 (20)

Anyone can tell me whether this is applicable to my design?

Thanks a lot for any reply
