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

Since the rotations in 3dvolreg are in degrees, those values
should be converted before taking the euclidean norm. One
option would be to multiply by 180/pi = 57.3, say. Assuming
the first three are shift and the next are rotations, they could
be applied via the 'weighted_enorm' function, rather than just
enorm, e.g.

-derivative -collapse_cols weighted_enorm \
-weight_vec 1 1 1 57.3 57.3 57.3 \
...

See 1d_tool.py -help, Example 9c, though it does not actually censor.

Note that 1mm is a fairly high threshold for censoring.
Are these subjects prone to motion?
