External Email - Use Caution hello, i would like to create a mesh, such as the one in surf/lh.pial, using an arbitrary binary volume.
i'm aware that freesurfer can convert the subcortical volume ROIs to surfaces, does anyone know if this can be applied to an arbitrary binary volume? i would like to replicate the script by Anderson Winkler (see below) but instead of on subcortical aseg, on an arbitrary volume that i supply. is this possible? thanks, # Pre-tessellate echo "==> Pre-tessellating: ${s}, ${lab0}" ${FREESURFER_HOME}/bin/mri_pretess \ ${SUBJECTS_DIR}/${s}/mri/aseg.mgz ${lab} \ ${SUBJECTS_DIR}/${s}/mri/norm.mgz \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}_filled.mgz # Tessellate echo "==> Tessellating: ${s}, ${lab0}" ${FREESURFER_HOME}/bin/mri_tessellate \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}_filled.mgz \ ${lab} ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}_notsmooth # Smooth echo "==> Smoothing: ${s}, ${lab0}" ${FREESURFER_HOME}/bin/mris_smooth -nw \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}_notsmooth \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0} # Convert to ASCII echo "==> Converting to ASCII: ${s}, ${lab0}" ${FREESURFER_HOME}/bin/mris_convert \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0} \ ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}.asc mv ${SUBJECTS_DIR}/${s}/tmp/${RNDSTR}/aseg_${lab0}.asc \ ${SUBJECTS_DIR}/${s}/ascii/aseg_${lab0}.srf
