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--

I am experiencing some inconsistencies when pulling out cluster coordinates. The output of 3dclust give slightly different coordinate values than the ones that I see in the AFNI gui with the report function. I typed on the command line: 3dclust -1Dformat -1thresh 8.23 5 -16 ANOVAfile+tlrc'[3]' > out.1D.

When I click the 3dclust button within the Afni report, the command given is:
3dclust -1Dformat -nosum -1dindex 2 -1tindex 3 -2thresh -8.23 8.23 5 432 ANOVAfile+tlrc. The output of this matches the coordinates in the gui report, but the mean value for many of the clusters is less than 1. Does this seem odd, as p<0.005?

Thank you,
Fatima
