This sample excludes a portion of subjects that have been included with the first acquisition (EEG: First Episode Psychosis vs. Control Resting Task 1), since they were collected using the same montage.\nThe subjects that have been excluded here and are included in Task 1 are: sub-2140A, sub-2170A, sub-2174A, sub-2176A, sub-2177A, sub-2184A, sub-2193A, sub-2214A, sub-2217A, sub-2221A.\nThe phenotype directory contains clinical assessment results and data divided by type for all subjects.
