Information about multiple comparisons correction has been pre-computed for various parameters, including the FWHM. In this case, the measured FWHM (38) is outside of the precomputed range. 38 is extremely high. Is this a thickness study? What smoothing level did you apply (--fwhm in mri_glmfit)?

Hi all,

I ran a multiple comparison correction for a surface based analysis with this command:

mri_glmfit-sim --glmdir rh.project.glmdir --cache 2 abs --cwpvalthresh .05 --2spaces

But I am getting the following error:

cannot find /usr/local/freesurfer/average/mult-comp-cor/fsaverage/rh/cortex/fwhm38/abs/th13/mc-z.csd

What might this error mean? I searched in the mail archives but could not get any proper answer. Kindly help me.

Thanks
