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

You want the "-warp" dataset to be the +tlrc dataset that you defined via the markers, etc. -- this is the one that has the transformation matrices between +orig and +tlrc coordinates. If you marked on dataset spgr+orig, then the "-warp" dataset should be spgr+tlrc.

If your mask contains more than one value (you drew several ROIs, each marked with a different dataset value), then you also want to use the "-vote" option to preserve these values.

Thus, I'd recommend something more like

3dfractionize \
-template 3dtimeseries+orig \
-warp spgr+tlrc \
-input ROImasks+tlrc \
-clip 0.2 -vote -prefix ROImask
