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 Brian,

Maybe you answered your own question for the first issue, but
to be explicit, the grid/resolution of your stats dataset is
probably not the same as that of the TT_Daemon atlas (1x1x1).

So in order to apply the atlas, you need to resample it to
match your stats dataset, which you do nicely via 3dfractionize
as part of your second issue.

Your use in the second issue looks good.

----

Note that you can test this. Instead of making just a temporary
mask, actually save it to a file. Then you can overlay it on
other datasets, and verify the mask location, resolution and data
value (such as the amygdala coming out as 71).

3dcalc -a 'TT_Daemon::amygdala' -expr a -prefix amyg.mask
3dinfo amyg.mask+tlrc
