Dear all,

           I am trying to run a group analysis between 2 groups of subjects. I did the mris_preproc and mri_surf2surf steps. When I set up my mri_glmfit, the end of the output is:

Reshaping mriglm->mask…

search space = 74485.691578

DOF = 1344

Starting fit and test

Fit completed in 0.481417 minutes

Computing spatial AR1 on surface

Residual: ar1mn=0.996928, ar1std=0.000586, gstd=7.275170, fwhm=17.131715

Writing results

    wholegrp_contrast

       maxvox sig=1e+10   F=33202.6 at index 0 0 0 seed=1396057719

mri_glmfit done

Now, from past experience, I know that the search space I get here is large. Why does my maxvox sig say infinite? Am I missing something? Has this happened to others?

Thanks

Koushik
