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

Greetings AFNI community,

I am that kind of guys who used to use SPM, but I tried to learn how to use AFNI recently. One problem that I can not figure out is I have the Canonical T1 image and my EPI images both in SPM Analyze format and they aligned with each other perfectly. But after I used "to3d" command to transfer both of them to AFNI format, then when I use "See Overlay" function in AFNI GUI to look at whether the Overlay (my EPI image) and Underlay (Canonical image) align well, I can always see a mismatch there.
Why it is the case? One thing I know is that T1 image has higher resolution: X*Y*Z = 91*109*91, resolution 2*2*2 mm^3. While the EPI image is only a X*Y*Z = 41*48*35matrix, resolution 4*4*4mm^3.
Any body can give me some advice about what is wrong here and how to correct it?

Thanks
Jian
