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.
The first question is, do the two groups have roughly the same average cost value? Or do they differ significantly? This question will have a big impact on your analysis result and interpretation. You may read the discussion about the centering issue in the 3dttest++ -help. Once this is clarified, we can talk about the result interpretation.
