The CSV file contains the cortical thickness (CT) and fractal dimension (FD) estimated from the brain MR T1-weighted images contained in the multicenter online repository Information eXtraction from Images (IXI) study. Each CSV file contains the following columns: Subject: id of each subject SITE: imaging site label (ABIDEI or ABIDEII followed by the institution name that collected the images; ICBM; NKI2) Age: each subject's age, expressed in years Sex: 0=male; 1=female. cortex_CT (FD): CT (or FD) of the cerebral cortical gray matter (GM). lh_cortex_CT (FD), rh_cortex_CT (FD): CT (or FD) of the left (lh) and right (rh) cerebral cortical GM. lh_frontal_cortex_CT (FD), rh_frontal_cortex_CT (FD): CT (or FD) of the left (lh) and right (rh) cerebral cortical GM of the frontal lobe. lh_temporal_cortex_CT (FD), rh_temporal_cortex_CT (FD): CT (or FD) of the left (lh) and right (rh) cerebral cortical GM of the temporal lobe. lh_parietal_cortex_CT (FD), rh_parietal_cortex_CT (FD): CT (or FD) of the left (lh) and right (rh) cerebral cortical GM of the parietal lobe. lh_occipital_cortex_CT (FD), rh_occipital_cortex_CT (FD): CT (or FD) of the left (lh) and right (rh) cerebral cortical GM of the occipital lobe.
