Hi,
I would like you use a parametric regressor as a "Task" in gPPI, but PPPI.m only searches the first item in the SPM.Sess.U.name structure (line 503). This is a problem because, as you know, any parametrics would be listed as subsequent names. Is there a way around this?

Also, a couple of other small things I found but have now found solutions/work arounds.
1. In your manual you refer to the P.Contrast field, and in your code it's P.contrast.
2. If I understood your manual/comments correctly, setting P.FLmask = 1 should mask the VOI with the mask.img that is in the first level directory -- is this correct? If so, I couldn't get that to work so instead used a struct for VOI listing the VOI .nii file and then the masks as the mask.img.

Thank you!
