External Email - Use Caution To find the code, look at FreeSurferColorLUT.txt, e.g., you may be interested in a subset of these:
grep -i vent $FREESURFER_HOME/FreeSurferColorLUT.txt The last 4 values on each line make up a color code (RGBA, in range 0-255 per channel). The first value is the region code, used in a segmentation file. So the voxels with intensity 14 in the file <subject>/mri/aseg.mgz should belong to the 3rd ventricle. I hope that is what you were asking?
