Hi Nick, please remember to post to the list and not to us personally. To answer your question, you could create an run an analysis with just the button press. Go into the analysis and get the button press regressor from X.mat, then save it as a text file in the run folder. Then make your analysis and specify this as a task regressor. I *think* that should work.

Thanks Doug,

This is actually a retinotopy analysis and the paradigm files are phase encoded. Is there any possible way to regress out the activity associated with the button presses.

Thanks for your assistance,

Nick

Why not include it as a condition in your paradigm file? doug

Dear Freesurfer Users,

I am trying to regress out the activity associated with button presses in my GLM analysis. How do I generate a nuisance regressor file analogous to a white matter regressor generated in functional connectivity (a one column time course file)?

Thanks you,
