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 Robin-

It is definitely hard to see all of the regions in the "Draw Dataset" plugin. I'll leave it to the AFNI guys to say if they can make a change to display the regions in a popup window.

I usually draw the atlas regions using the command line tool whereami. Using that tool, you can get a list of all of the atlases in AFNI using the following:
whereami -show_atlases

You can then display all of the regions in a particular atlas using the following:

whereami -atlas CA_N27_ML -show_atlas_code

And finally, can use the information from that point to create an atlas region ROI doing something like this (you can also substitute the number instead of the name):
whereami -mask_atlas_region CA_N27_ML:left:middle_frontal_gyrus -prefix left_mfg

The TT_Daemon that you're typing is using whereami to lookup the region using the Talairach Daemon and then filling in the associated voxels. Some more information here.

Some additional ways of drawing ROIs here. In addition to creating the ROIs separately and then using them in other programs, there is a somewhat not-so-secret way of quickly creating atlas regions using other programs (like 3dresample or 3dfractionize):

3dfractionize -template someBrain+tlrc. \
-input CA_N27_ML:left:middle_frontal_gyrus \
-preserve -clip 0.2 -prefix L_MFG
