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

Gotcha!

Gang,

One more point for one of the covariates. The covariate called Accuracy is actually a binary number when considering the trial data: 1 = correct and 0 = incorrect. In that case, would you proceed the same way to subtract the group mean for each condition of interest (i.e. Time1, Time2, Time3, and Time4)? For example, if the average accuracy for Time 1 across all participants is 88.7% correct, then would I subtract 88.7 from a 1 or a 0, depending whether the trial was correct or incorrect, respectively. Something seems weird about this approach with a binary variable.

Best,
Christine
