RE: covariates
Hi Jeff,

I followed your advice and ran the calc properties step without any covariates. Now at the GLM stage, I am unable to enter the contrast weights for my IVs (which were entered in the calc properties step without any issues; see attached image). As an alternative, I tried re-entering the IVs by selecting new predictors. However, I am immediately getting the same error as before, "Error using horzcat. Dimensions of matrices being concatenated are not consistent."

I tried entering the IVs as 1 combined matrix (2 columns X 38 rows) and as separate matrices (1 X 38), but am still getting the same concatenation error. Is there some other format in which I need to set up my predictors?

A related concern is that I'm not being able to enter in my covariates as predictors (which I would weigh as 0 in the contrasts to partial out their variance), due to that same error. However, I believe that once the horzcat error is resolved I'll be able to enter in all my IVs and covariates. 

Please let me know your thoughts.

Thank you!
Heena
