List of the most informative features.
| Rank | Frequency of appearance (out of 50) | Name of network measure | First Anatomical Region with the highest overlap (% overlap) | Second Anatomical Region with the highest overlap (% overlap) | d’(p-value) | Single feature classification |
|---|---|---|---|---|---|---|
| Functional atlas | ||||||
| 1 | 21 | Distance | Left Middle Temporal Gyrus(53), Left Superior temporal Pole(19) | Right Inferior Occipital Cortex(39), Right Lingual Gyrus(17) | 0.87(<0.001) | 69% |
| 2 | 12 | Generalized Topological Overlap | Left Middle Temporal Gyrus(53), Left Superior Temporal Pole(19) | Right Inferior Occipital Cortex(39), Right Lingual Gyrus(17) | -0.88(<0.001) | 69% |

From left, column 1: Rank of the feature in terms of frequency of appearing in the selected feature set; column 2: Number of appearances in the selected feature set; column 3: Name of network measure, all measures characterize relationship between pairs of nodes (regions); column 4: First region corresponding to the measure. Regions of the functional atlas do not have labels. To indicate their anatomical location, the two anatomical regions from the AAL atlas with the highest overlap are listed. The number in () shows the percent overlap; column 5: Same as column 2 for the second region corresponding to each region; 6th column: Sensitivity index, also known as d’and the 2 sample t-test p-value in () comparing distribution of each feature across the control and schizophrenic population. A positive d’ value indicates that feature values are higher for the patients compared to control subjects; column 7: Performance of each feature on its own.
