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 Kara,

Those scripts are for rotating wedges and expanding rings. In your case, I suspect it is best to process the data with linear regression using as many stimulus classes as you have discrete stimulus positions (2 or 4?). From this you can create maps showing the responses to each of the meridia and then draw the boundaries accordingly.
It would be best to use afni_proc.py to perform the regression analysis. To get an idea of what that entails, run afni_proc.py -h_view, and search for example "8. Based on subject FT under AFNI_data6".
I don't know how familiar you are with processing data on the surface so if some steps are not clear let me know and I can elaborate.

cheers,
Ziad
