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

The missing scaling info was:
[* 0.00100329] -26.548 to 30.0715 [scaled]


I guess I was under the impression that after using 3dmerge all of the voxels below the threshold criteria would be 0, even after the Talairach transformation. This is how it appears when viewing the Patterns_act1tlrc data set (fim data set, Func listed as 0 for the voxels in question), but there seems to be values greater than 0 when 3dmaskave or 3dcalc is used. Normally I threshold data (3dmerge) in the original format and then apply the Talairach transformation. Would it be more accurate to transform the functional data set first (results from 3dDeconvolve) and then apply the threshold (3dmerge)?
