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

There are a few ways to transform to Talairach space from MNI space.

# for N27 in MNI (MNI_N27) space data, this works best
adwarp -prefix tt_testmni_region -resam NN -apar TT_N27+tlrc -dpar testmni_regions+tlrc. -force
# Use the two-part Brett transform for the ICBM452 or MNI-152 datasets, this probably works better
3dWarp -mni2tta -NN -prefix tt_testmni_region_brett+tlrc testmni_regions+tlrc.
# color in AFNI with separate colors per region
3drefit -cmap INT_CMAP testmni_regions+tlrc.
3drefit -cmap INT_CMAP tt_testmni_region*+tlrc*.HEAD

You could also use the Lancaster transformations too. See this previous post for some gory details. Check your results in the afni GUI.
