[Freesurfer] FreeSurfer Stats files: format of 'Measure' lines

External Email - Use Caution

Dear FreeSurfer experts,

I'm parsing data from FreeSurfer stats files, e.g., <subject>/stats/lh.aparc.stats and aseg.stats.

My question: when parsing measure lines, which combination of fields are guaranteed to uniquely identify a measure? Here are two example lines (from aparc.stats):

# Measure Cortex, NumVert, Number of Vertices, 140843, unitless # Measure Cortex, WhiteSurfArea, White Surface Total Area, 94426.8, mm^2

If you ignore the line header part '# Measure ', each line consists of 5 fields. Is it, for example, safe to assume that the combination of the first 2 fields ("Cortex" + "NumVert" for the first example line) is unique?

Thanks in advance,

Tim
