No, it will re-run and re-write the analysis, but that usually only takes a few min and the results will be identical. BTW, you can give it multiple contrasts on the cmd line.

Hi,

Just a very quick question about the glmdir flag for mri_glmfit when running the group analysis via command line:
If I am interested in multiple contrasts, can glmdir be the same for subsequent iterations of mri_glmfit with different contrast vectors?
(I understand that each contrast comes up as a corresponding subdirectory... but are there any issues with overwriting any files in the glmdir?)

Thanks,
- Jerry
