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

Wiktor,

I cannot offer an exact explanation for such discrepancies. One possibility is a data precision issue; if so, add option "-datum float" to your 3dcalc command and see if that makes any difference.

A side note: you can use "3dmerge -1zscore ..." to the whole file, and it will convert all the statistics sub-bricks in the file to Z-stat (and keep anything else intact). At least it works for AFNI format. Not so sure about NIfTI files, though.
