Hi Doug,

 

Thanks for getting back to me! I’ll have a go at the command-line stream and see if that makes a difference.

 

Many thanks!

It might be that the design matrix is ill-conditioned. Did it print
anything to the terminal? Also, we are not really supporting qdec
anymore, so you can try using the command-line stream (ie, mris_preproc,
mri_surf2surf, mri_glmfit, mri_glmfit-sim)
