Re: [Freesurfer] cluster size threshold
You need to find the correct CDF file, eg, if the final FWHM is 12, it would be in $FREESURFER_HOME/average/mult-comp-cor/fsaverage/lh/cortex/fwhm12/abs/th30/mc-z.cdf To get the FWHM look in glmdir/fwhm.dat and round down in the mc-z.cdf file, find the row where the MaxClustCDF drops below .05/2=.025, then look at the MaxClustBin for the critical cluster size On 2/24/2020 6:49 AM, Elisa Castaldi wrote: External Email - Use Caution Dear experts, To perform a Monte Carlo based cluster correction, I have run the following line: mri_glmfit-sim --glmdir glmdir --mczsim 3 abs --cwp 0.05 --2spaces --a2009s I need to figure out which is the minimum number of voxels required for a cluster to be considered significant.

Re: [Freesurfer] Cluster size threshold for the sig.mgh file
Use the --minarea option doug Jürgen Hänggi wrote: Dear FS experts We would like to threshold the cluster size in the sig.mgh image in order to exclude clusters that are only a few vertices in size, but I cannot find this option Is it possible to do it within FS? If yes, how to do it? Thanks in advance Regards Jürgen Juergen Haenggi Ph.D. (Dr. des.)
