(a) Frontal-limbic and frontal-parietal FCs were highly consistent in all the SZ diagnosis (TR-SZ vs. HC, NTR-SZ vs. HC, TR-SZ vs. NTR-SZ). (b) Consistent frontal-limbic, frontal-parietal and occipital-temporal FCs were correlated with the disease duration, PANSS negative and OLA-ED. (c) Classification accuracy comparisons over the three atlases under 2 feature selections, and 4 classifiers.
