Data file (subject characteristics, volume and shape)
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
In this data file the columns from left to right represent Diagnosis (dx=diagnosis, T = TS or chronic tic disorder, C = Control), Sex (m = male, f = female), Age at scan (in years), and handedness (L = Left, R = Right, A = Ambidextrous). Then the shape principal component (eigenvector) values are represented as demonstrated by the following example: “NaLpc01” = nucleus accumbens (Na) Left (L) principal component (pc) 01. (“Na” = nucleus accumbens, “Cd” = caudate, “Pl” = globus pallidus, “Pu” = putamen, “Th” = thalamus). Next the volumes are listed using similar notation, e.g. “volCdL” = volume in mm3 (vol) Caudate (Cd) Left (L). Finally, Freesurfer analysis values are listed using their standard notation, which can be found in the table at: http://ftp.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI#aseg.stats - See more at: http://188.8.131.52/black/#sthash.OO28vyHo.dpuf
