Hi all,

I am using a template GLM processing stream but its producing HRF with very strong periodic elements.

Am I doing anything wrong? Any insights here would be great.

Thanks

I suggest you set your rhoSD_ssThresh to 0.

it looks to me that you are viewing short separation channels and you have regressed out the short separation signal which is resulting in the very small values (you have 1e-11).
