The HCP-EP Release 1.1 contains behavioral data for 252 subjects (69 subjects added since the 1.0 release). In addition to the added subjects for the Clinical Assessments and Procedures, corrections were made to behavioral data for a few subjects. Cohort assignment is as follows: 57 affective, 126 non-affective psychotic patients and 68 matched healthy controls. Updated MRI data (several data files were missing from the preprocessed Structural imaging data in the 1.0 release) is provided for 183 of these subjects, 169 with preprocessed structural data (the same group of subjects as in HCP-EP Release 1.0). Modalities include structural MRI, resting state fMRI, and diffusion MRI. For details of all the measures included in this release and access instructions see the 1.1 Release documentation at https://www.humanconnectome.org/study/human-connectome-project-for-early-psychosis/document/hcp-ep.
