If you have a full-width half-max (FWHM) for your analysis, you can convert your z into a sig (-log10(p)*sign(z)), then run mri_surfcluster. You should give it a CSD file that corresponds to your FWHM, the sign of the contrast you are interested in, and the voxel-wise threshold. The CSD files are located here $FREESURFER_HOME/average/mult-comp-cor doug

Hi List, I have a question on how to write out the matlab vector containing the Z-statistics and perform subsequent multiple corrections. I already read some functions and know how to write it to a mgh surface file. Here, my question is 'is there any specific things on the header of the surface file, which allows me to do cluster-wise correction (see corrected p-value < 0.025) if there is such a command for that?'. Thanks!
