Hi!

A quick follow-up:

I have a taskreg file with 6 continuous predictors. I would like to run specific contrasts, e.g., predictor 1 vs. mean(predictor 2:6).

From what I gather, selxavg3-sess will run automatic contrasts on taskregs, but the automatic contrasts are against baseline. This is not what I need at this point.

mk-contrast-sess does not like what I am putting in because I do not have a paradigm file in which condition numbers are specified.

Is there a way to compute specific contrasts between multiple taskregs, and if not, is there a workaround?

Thank you very much, Caspar

Hi!
I have several external regressors in my analysis that I configure with -taskreg in mkanalysis-sess (something like -notask -taskreg nameoffile 6).
I was wondering how to set up mkcontrast-sess to contrast these regerssors given that I do not have a paradigm file for them.
Can I just do something like -a 1 -c 2 -c 3 -c 4 -c 5?

Thanks, Caspar
