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:

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

Hello,

I have three datas: A+orig, B+orig and C+orig.

first, I use "3dresample -master C+orig" to resample B+orig and A+orig.

Then I run " 3dcalc -prefix D -a A+orig -b B+orig -c C+orig -expr 'a*(c-b)'.

I got one warning message:

*+ WARNING: dataset 'c'=./C+orig.BRIK has an obliquity difference of 17.978367 degrees with ./A+orig.BRIK

Could you tell me what is the problem? How could I figure this out?

Best,
Pengmin
