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

Hello,
I am using 3dttest++ to explore associations between seed-to-voxel resting state connectivity and scores on a performance-based assessment of function in a sample of patients with schizophrenia. I am using the recommended -Clustsim option in 3dttest++ to use the permutation method to simulate the noise volume to identify clustersize thresholds for a set of voxelwise p-values. I was hopi

Thanks so much, Daniel. That's clear. I should be good to go!
Hope you had a nice weekend,

Hi Daniel,
Thanks for the suggestion. The two 3dWarp commands simply took a mask of leftMFG+tlrc as input and applied a transformation to produce an output file in MNI space with the specified prefix. I am looking over the 3dfractionize example and want to make sure I properly specify the commands (Example: 3dfractionize -input dset+tlrc -warp ~/abin/TT_N27+tlrc -prefix dset_mni -template temp

Hi,
I want to create a binary mask of the left rostralmiddlefrontal region from the Desikan-Killiany probabilistic atlas, TT_desai_dkpmaps+tlrc, so I ran the following command (to get a mask of all voxels > 25% in the probabilistic atlas):
3dcalc -a 'TT_desai_dkpmaps+tlrc[19]' -expr 'ispositive(a-0.25)' -prefix leftMFG
My first question is: Does this step yield a b

Good morning,
I am new to using AFNI (I've mostly used SPM). My background is mainly in resting-state fMRI doing ALFF and functional connectivity analyses of schizophrenia patients and healthy controls. To get familiar with AFNI, I am trying to do some simple analyses of seed-to-voxel connectivity in 100 schizophrenia patients and 111 controls. I preprocessed the data, and have performed
