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

I'm interested in creating a mask that contains the 2000 most significant voxels in one of my stats subbricks. A sluggish way to do this would be to go back and forth adjusting the threshold slider in the AFNI gui and adjusting the cluster threshold until I get a few clusters that remain that add up to 2000 voxels total and save this as a mask via the report window, but I'm hoping for s

I'm doing a sanity check with my auditory fMRI task and am trying to get 3dsvm to classify sound=1 vs no sound=0.
when running this script:
3dsvm -testvol run6_detrended+tlrc. -model model_runs1thru5+tlrc. -testlabels 36289_MVPArun6.1D -predictions pred6_model1thru5
the predictions that are spit out are not zeros and ones, but fractions (e.g.
0.042139769
0.85066682
0.79669857
