This dataset was curated by downloading the Harvard oxford time-series for UCLA and UM sites from the Preprocessed Connectomes Project. Since the original ABIDE data was released under the CC-BY-NC-SA license. The same applies to this dataset as well.

ABIDE I FreeSurfer 6 'local gyrification index' (lGI) data

DOI of this dataset: 10.5281/zenodo.7132610

This directory 'abide_freesurfer6_lgi' contains the ABIDE I FreeSurfer 6 'local gyrification index' (lGI) data and meshes.

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."

How this data was produced

The following steps were used to create the data:

• We downloaded all available MRI scans for the ABIDE I subjects (1035 subjects).
• We pre-processed all subjects in FreeSurfer version 6 (https://freesurfer.net) by running the full recon-all pipeline for each subject.
  • We did not run any quality metrics on the scans or exclude any subjects.
• We computed pial-lgi (Schaer et al. 2008, https://doi.org/10.1109/TMI.2007.903576) as implemented in FreeSurfer 6 for all subjects.
  • For some of the subjects, MRI data was not available or lgi could not be computed due to very bad quality of the (or a completely failed) surface reconstruction. These subjects are listed in the file 'subjects_lgi_computation_failed.txt' (14 of 1035 subjects).
  • All subjects for which lgi computation succeeded for both hemispheres are listed in the file 'subjects.txt' (1021 of 1035 subjects).

Contained files

• In order to reduce the size of this dataset, for each subject, we only included the following files:
  • /surf/lh.pial : the pial surface mesh for the left hemisphere, in FreeSurfer surf format.
  • /surf/rh.pial : the pial surface mesh for the right hemisphere, in FreeSurfer surf format.
  • /surf/lh.pial_lgi : the per-vertex lgi values for the left hemisphere, in FreeSurfer curv format.
  • /surf/rh.pial_lgi : the per-vertex lgi values for the right hemisphere, in FreeSurfer curv format.

See the section 'How this data was produced' for information on the files 'subjects.txt' and 'subjects_lgi_computation_failed.txt'.

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.
• The lgi values are only contained in native space. Standard space data is available as a separate download on Zenodo.
