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 Gang,

Getting back to this thread after some time away. I'd like to take a fresh shot at using 3dLME with a structural analysis. I have two groups of subjects with up to 4 timepoints per subject. However, some subjects have as little as one timepoint.

Instead of including a variable that notes the duration between scans (which would cause missing data for subjects with only one scan), could I instead have a variable that denotes time since baseline? This would mean that all subjects could be included in my analysis.

Thanks,
Lara
