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

Hi Regan,

Thanks for the data. It looks possible that the t to z conversion might have precision difficulty for large t-stats.

However the main problem is more simple than that. You have doubled the degrees of freedom in the commands, since the input is specified as:

-setA shellgame_*_belvthink_resampled*

But these files are .HEAD and .BRIK *pairs*. The input should be specified as:

-setA shellgame_*_belvthink_resampled*.HEAD

That will cut the DoF in half, and lead to more reasonable results.
