No formal quality assurance checks were made on the software, and no formal support or maintenance is provided or implied. The code is written using only basic Matlab functions to try to maximize platform compatibility.ĭisclaimer: This software is made available to promote better understanding and quality review of fMRI data.

More recently, the programs are run at our lab using Matlab R2013 and Mac OSX 10.8. The programs have been tested in Matlab Versions 6.5 - 7.7 on RedHat Linux and Windows XP. The ArtRepair programs use the SPM read/write capabilities, and thus use AnalyzeFormat images with SPM2 and Nifti images with SPM5 and later. Requirements: These programs assume that MATLAB and SPM are installed. Please note that the script is not in the spm_jobman format, and it requires that the user be familiar with Matlab to use it.

Step-by-step instructions for running ArtRepair. (This document describes only the functions present in the earliest software versions). Overview presentation of the initial software features. This software has been downloaded by more 3000 neuroscientists around the world. This neuroimaging research and method development is supported by the National Institute of Mental Health (NIMH), Grant Number K25MH077309. New features in Version 4 include motion adjustment without using motion regressors, new despike and detrending algorithms, and techniques for quantifying estimates into percent signal change. ArtRepair Version 4 was released on June 16, 2009. The software is a written as a toolbox for SPM. This version is designated beta because it is not as thoroughly tested in SPM12 as in SPM8. Version 5b includes upgrades for compatibility with SPM12. Since task-correlated motion may strongly affect estimation accuracy for a high motion subject, additional group level quality checking tools are provided to allow easy review of single subject estimates, and to help identify outlier subjects in group analyses.

The ArtRepair algorithms are formulated as preprocessing steps that clean up noisy data before reaching the General Linear Model (GLM) in particular, the motion adjustment algorithm is an alternative to adding motion regressors to the design matrix. Diagnostic viewing tools and metrics allow quality checking at every step in the analysis. The algorithms can reduce the residual errors that occur after realignment, and can automatically detect and remove noisy volumes, slices, trends, and voxel-wise spikes in the data.

The ArtRepair software suite is a set of special methods to improve the fMRI analysis for high motion pediatric and clinical subjects.
