# ABIDE I FreeSurfer 6 'label' data This archive contains the following ABIDE I FreeSurfer 6 labels: cortex, aparc, aparc.a2009s. ## Credits This data is derived from the MRI scans of the ABIDE I dataset: * ABIDE I dataset: https://fcon_1000.projects.nitrc.org/indi/abide/ Quoting from that website: "The Autism Brain Imaging Data Exchange I (ABIDE I) represents the first ABIDE initiative. Started as a grass roots effort, ABIDE I involved 17 international sites, sharing previously collected resting state functional magnetic resonance imaging (R-fMRI), anatomical and phenotypic datasets made available for data sharing with the broader scientific community. This effort yielded 1112 dataset, including 539 from individuals with ASD and 573 from typical controls (ages 7-64 years, median 14.7 years across groups). This aggregate was released in August 2012. Its establishment demonstrated the feasibility of aggregating resting state fMRI and structural MRI data across sites; the rate of these data use and resulting publications (see Manuscripts) have shown its utility for capturing whole brain and regional properties of the brain connectome in Autism Spectrum Disorder (ASD). In accordance with HIPAA guidelines and 1000 Functional Connectomes Project / INDI protocols, all datasets have been anonymized, with no protected health information included."

All files are in ASCII FreeSurfer label format. For the annot files, see FreeSurferColorLut.txt that comes with FreeSurfer for meaning of integers specifying a region. ## What is NOT contained * The ABIDE demographics information (metadata on the subjects, like age, ...) is not included, you can get it from the ABIDE website. ## Author and License Note: For the authors of the original ABIDE I dataset, see the Credits section above.
