I just read this statement : “ A newer version of mri_mcsim for linux can be obtained from here: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.3.0-patch/mri_mcsim.linux Copy it to $FREESURFER_HOME/bin/mri_mcsim “ here: https://surfer.nmr.mgh.harvard.edu/fswiki/BuildYourOwnMonteCarlo

I am working with FreeSurfer6, should I update it or it was implemented in the version 6?
