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

I can answer the 'wierd results' question. 3dROIstats uses the actual value stored in the mask, not the scaled version if there is a scaling factor. It looks like in some cases, only one ROI survives your 3dcalc command. For whatever reason, 3dcalc has decided to scale this (e.g. store 1 as 255 with a scaling factor of .0039). You can prevent this by using the -nscale option in your 3dcalc command.
