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 all

I have a statistical bucket, run1.gam.stat+tlrc, consisting of 8 sub-briks:

Sub-brik 0: effect1 LC[0] coef
sub-brik 1: effect1 LC[0] t-stat

sub-brik 2: effect2 LC[0] coef
sub-brik 3: effect2 LC[0] t-stat

....

sub-brik 6: effect4 LC[0] coef
sub-brik 7: effect4 LC[0] t-stat

I tried to convert the bucket to a corresponding bucket where the coef sub-briks remain unchanged and the t-stat sub-briks are converted to z-score, with the command:

3dmerge -doall -1zscore -prefix run1.gam.stat.z run1.gam.stat+tlrc

but that seems to alter also the coeff sub-briks, not just the t-stats, as I thought it would do from the help of 3dmerge. Am I misunderstanding the help? Are the LC[0] coeff sub-briks considered statistical briks too?

thanks in advance

giuseppe
