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,

I need help in merging ROI masks. I have two masks created using draw dataset plugin. One mask has 7 ROI's and other has 6 ROI's. I merged the two masks together using the 3dcalc command.
3dcalc -nscale -a roi+tlrc -b roi_stria+tlrc -prefix tmp -expr 'a+b'
When I edit the merged ROI's again using draw dataset plugin, the values of the corresponding ROI does not remain the same. i.e., Suppose if the ROI with value = 1 had green color in the merged one, it turns out to be yellow after editing.

Any help would be highly appreciated.

Thanks
Hema
