Is this volume data? If so, then use --grf with mri_glmfit-sim instead of --cache. doug

Dear Doug,

Can you please advise me how I can do a multiple comparison for my DTI group analysis?

I tried and I ran:

mri_glmfit --y group-fa-tal.nii --fsgd DTI_group_analysis.fsgd dods --cwpvalthresh .99 \ --C contrast.mtx --glmdir group_analysis-0.99.glmdir

but I got:

ERROR: Option --cwpvalthresh unknown so I really don't know how I can do the multiple comparison in this case: the DTI data.

Also, I tried to run the:

mri_glmfit-sim \ --glmdir group_analysis.glmdir \ --cache 2 neg \ --cwpvalthresh .99 \ --overwrite

but I got another ERROE:

ERROR: cannot find /usr/local/freesurfer//average/mult-comp-cor///cortex/fwhm04/neg/th20/mc-z.csd

Thank you very much! Antonella
