Preprocessed ABIDE Dataset

ABIDE Dataset Description

ABIDE(Autism Brain Imaging Data Exchange) Dataset 1 contains 1112 dataset, including 539 from individuals with ASD and 573 from typical controls (ages 7-64 years, median 14.7 years across groups).

Acquisition protocol

  • Resting state fMRI (R-fMRI)
  • Anatomical dataset
  • phenotypic dataset

Scanning Location

  • involving 17 international sites

Preprocessing

The T1 MRI data were used and preprocessed to generate normalised brain volume maps. The grey matter (GM) and white matter (WM) images were analyzed together.

Steps

  1. AC-PC Realignment
  2. GM, WM Tissue Segmentation
  3. Non-linear registration to MNI152 space
  4. Normalization
  5. Resampling
  6. modulation
  7. 4mm Smoothing

Results

The result, normalized brain volume map, has shape of 121x145x121. Each voxel in the volume map represent regional volume of tissue.

Software Environment

All images were pre-processed using SPM12 in the MATLAB R2018a environment. DARTEL which is one of the SPM extension was used for normalization, non-linear registeration, resampling, modulation and smoothing step.

Preprocessing Reference

We followed the protocol from the paper "Predicting brain age with deep learning from raw imaging data results in a reliable and heritable biomarker" by James H. Cole et al. For the very detailed preprocessing tutorial of Voxel-based Morphometry(VBM), see here
