That column looks to be all 0s. This is the problem.

Basically, you can't form a contrast for a regressor that does not exist.

Hi everyone,

I am getting an error that I can't diagnose... any help would be appreciated.

Attached are the .mat files for a first level specification. Everything
seems to be running fine until it gets to contrast 11 when it crashes. The
only hint at a problem I have is from looking at the design matrix (image
also attached). Contrast 11 is '1' contrast above the regressor in session
2 where there looks like there is a problem. I've looked at my code, the
mat files attached, and the matlabbatch stucture generated by my script to
specify all the .mat files and i can't find a problem.

Anyone have any idea what's going on?

Thanks,
Lorelei
