Automatic Analysis software was originally developed by Dr Rhodri Cusack for supporting research at the MRC Cognition and Brain Science Unit. It is made available to the academic community in the hope that it may prove useful.
Definitions: aa means the Automatic Analysis software package and any associated documentation whether electronic or printed.
Use of this software is subject to the terms of the license, found in the license.txt file distributed with this software.
aa is a pipeline system for neuroimaging written primarily in Matlab. It supports SPM 12, as well as selected functions from other software packages (e.g., FSL, Freesurfer). The goal is to facilitate automatic, flexible, and replicable neuroimaging analyses through a comprehensive pipeline system.
More information can be found on the wiki.
- System: Linux or MacOX (Windows is not supported. Sorry!)
- MATLAB - It has been tested with version r2013a and later
- SPM - It has been tested with versions SPM12 and later (SPM12 r7487 is recommended!)
- Recommended software for features:
- For MEG (maxfilter): Neuromag (Elekta Instrument AB Stockholm, Stockholm, Sweden)
- For visual representation of the pipeline: GraphViz
- Recommended/Partially supported software for analysis:
aa is maintained on github.
Unzip the downloaded package, and add the main folder to the MATLAB path.
Some parameters (path settings, format settings) stored in /aa_parametersets/aap_parameters_defaults.xml have to be configured to reflect your local environment. We recommend naming your local configuration file aap_parameters_user.xml if you want to run the examples easily (see below).
Instead of copying the main aap_parameters_defaults.xml, we recommend to create a local version by inheriting most of the settings from aap_parameters_defaults.xml. See aap_parameters_defaults_CBSU.xml as an example.
directory_conventions/rawdatadir: Directories to find raw MRI data
sprintfformatting string to get subject directory as stored in directory_conventions/rawdatadir
sprintfformatting string to get series directory as stored in subject directory
directory_conventions/protocol_structural: Name of the structural/anatomical protocol as stored in the DICOM header
directory_conventions/dicomfilter: Directory listing filter to find DICOM data
directory_conventions/spmdir: Path to SPM. N.B.: You should not modify SPM version in your user script but rather in your local parameter file. Optional:
For distortion correction using fieldmap:
- directory_conventions/protocol_fieldmap: Name of the fieldmap protocol as stored in the DICOM header
For multichannel segmentation using T2-weighted image:
- directory_conventions/protocol_t2: Name of the T2-weighted protocol as stored in the DICOM header
- directory_conventions/rawmegdatadir: Directories to find raw MEG data
sprintfformatting string to get subject directory as stored in directory_conventions/rawmegdatadir
- directory_conventions/neuromagdir: Path to Neuromag (maxfilter)
Optional analysis software:
FMRIB Software Library:
- directory_conventions/fsldir: Path to FSL
- directory_conventions/fslsetup: Path to FSL setup/configuration script to be executed before any FSL command
- directory_conventions/fslshell: Shell used to run FSL. It should be in accordance with directory_conventions/fslsetup
- directory_conventions/fsloutputtype: Output type used by FSL ("NIFTI" recommended)
- directory_conventions/freesurferdir: Path to FreeSurfer
- directory_conventions/freesurfersetup: Path to FreeSurfer setup/configuration script, executing before any FreeSurfer command
- directory_conventions/freesurfershell: Shell used to run FreeSurfer. It should be in accordance with directory_conventions/freesurfersetup and directory_conventions/freesurferenvironment
- directory_conventions/freesurferenvironment: Path to FreeSurfer environmental setup script, executing before any FreeSurfer command
directory_conventions/eeglabdir: Path to EEGLab
directory_conventions/GIFTdir: Path to GIFT
directory_conventions/ANTSdir: Path to ANTS
directory_conventions/fieldtripdir: Path to FieldTrip
directory_conventions/BrainWaveletdir: Path to BrainWavelet
directory_conventions/spmtoolsdir: Path to external/custom SPM toolboxes
- directory_conventions/qsubscheduler: MATLAB function to set up qsub scheduler to execute jobs in the cluster (should be in your MATLAB path)
- directory_conventions/poolprofile: MATLAB function to create cluster profile for parallel processing in a local job (should be in your MATLAB path)
The user scripts and task lists in the examples folder demonstrate a wide range of analyses. It is easy to get started with AA by adapting the example that most resembles your planned analysis. Before you do that, we recommend that you try to run a few these scripts to confirm that your installation is running (e.g., aa_user_demo.m).
We provide rudimentary automated tests under the aa_test folder. If you are having trouble with AA it's a good idea to start by checking that you can get the automated test to run.
Help and support
Please feel free to open an issue here on Github if you are having trouble getting AA to work.
There is also a discussion list:
The master branch on github is only updated after testing, so this version is the one to use. Developer versions are maintained in each developer's AA fork on Github.
