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

Hey

(1) How did you mask out your data with the two simple effects of A and B? Could you provide your script for the masking?

We the p value at 0.0001 and determined the t-statistic for that value and used a 3dmerge command line. For example: 3dmerge -1thtoin -tindex # -1clip 6 -1clust 1.8 200 -prefix name.0001 input
Where 6 is the t-value at a p of .0001 and our connection radius is 1.8 and our clust size threshold is 200 1*1*1 voxels.

(2) During which step was the Gaussian blurring done, before or after 3dDeconvolve?

We Gaussian blurred after 3dDeconvolve. It is essentially the last step we do before inputing it into our ANOVA's. Except when we want to do this ORmask preANOVA masking, that masks out all non-significant voxels for main effect A and B.

Thanks so much for your time!
Jeremy
