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

I have made a second level analysis through uber_ttest.py and would like to estimate the significance of a cluster.

-fwhm s, is this in mm FWHM?

The amount of smoothing, can I use the estimated blur from a single subject?

blur estimates : 6.50091 6.22995 6.48386

e.g. use -fwhm 6.5 ?

3dFWHMx says that a stats image should NOT be used, but the folder for the group results only contains a stats file, and no file for the GLM errors?

-mask mset, which mask should I use? For example mask_anat.subject1+tlrc or TT_N27+tlrc ?


It would be nice if uber_ttest.py contained an option "Run cluster simulation", as uber_subject.py
