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 Daniel,
Thank you for your response. Yes please, can you send me instructions on a better way to upload data?
Also, is there anything in particular you'd like me to send you?
Best,
Tadeus

Hello,
We are running a lot of subjects using the standard proc.py process and we have identified patterns/abnormalities among the subjects. We are not sure if these patterns are acceptable as is or if we need to run additional functions to get a better alignment. We've categorized the patterns into 6 types of groups:
- Chunk missing from OFC
- OFC shifted up
- Halo/Ghosting
- Parietal

Hi Gang,
Thank you for the suggestion! I decided to go with the 3dMVM approach and it looks like the script is now running.
Best,

Hi Everyone,
I have 2 groups and 2 conditions. I looked at the interaction between the group and condition(GroupAvGroupB x Condition1vCondition2);
However, I would like to see if these results hold after factoring out or controlling for a possible covariate (such as Age)
So I want to look at Group A vs Group B x Condition 1 vs Condition 2 - while controlling for covariate.
Can anyone

Hi Everyone,
We're trying to look at our baseline activation so we can compare to our other vectors; however, we don't really know what to make of the output it produces. (E.g what to look at for Olay/Thrs in afni, what 0 1 2 3 for each run stand for (we have 4 runs in this paradigm)),
Below is our script and under that is the 3dinfo.
Thank you!

Thank you both for your inputs! Your answers have confirmed our decision to use the original (higher) resolution image instead of downsampling to match the scanner's resolution.
We have been using the afni_proc.py script to do the majority of our analysis; however, for skull stripping and registration, we've been using the "flirt" command from FSL.
Thanks again!

Hi Everyone,
The scanner we're using on has a resolution of 3.4mm voxels. From SPM, we were able to get an MNI template that has a 2mm resolution. We want to use this MNI template as our reference point when registering our anatomy and bold files. Is it better to convert the higher resolution (2mm) MNI to a lower resolution to match the data that we acquire (3.4) using fractionize or is i
