Automatic analysis (aa)
Automatic analysis (aa) is a pipeline system for neuroimaging, written in Matlab. It supports SPM 5/8 and some functions from FSL.
For more information see:
Any problems, report them to Danny Mitchell (version 2 and 3) or Tibor Auer (version 4).
Paths to aa
Different versions live in:
legacy versions (0.1beta - 2.0) - unsupported
/imaging/local/spm/aa/aa-ver0.1_beta
/imaging/local/spm/aa/aa-ver0.2_beta
...
- old versions (2.2 - 4.beta)
/imaging/local/spm/aa_svn_new/versions/release-2.2
/imaging/local/spm/aa_svn_new/versions/release-3.0
...
new version (4.0 - 4.1) (based on the latest devel-share branch from GitHub)
/imaging/local/software/AA/release-4.0
/imaging/local/software/AA/release-4.1 - recommended
Using aa
Configration
Before running aa you need to add the corresponding path to MATLAB Path:
- File/Set Path...
addpath('path_to_aa'); savepath;
To avoid version conflicts make sure that it is added to the top of the Path. It is even more important that path_to_aa/extrafunctions/spm_mods is on the top, so modification to the spm may have effect.
Running
Then, you need a User Master Script (UMS)
Advanced Features
Input file
It is possible to specify Subjects, Sessions and Events based on a text file. Required options in aap.acq_details.input (see also aap_parameters_defaults.xml):
- list: text file:
- Required format:
- a CSV file: cells are separated with semicolon
- subcells are separated with "_"
- a header in the first line
- Required columns (may contain more):
- "ID": numbers for identifying subjects
- "FMRI1": cells for the fMRI measurement; it must contain the same number of subcells as the coresponding column header
- first subcell is the CBU volunteer number (without "CBU")
- series numbers are defined in the consecutive subcells with the same order as their names in the coresponding column header
- E.g.:
- As "pure" text:
- ID;Age;Sex;FMRI1_Loc_Con_LDeasy_LDhard
- 02;29;f;90952_7_6_4_5
- Required format:
- selected_sessions: subselection of a subset of series:
E.g. (based on the example above): [3 4] --> LDeasy and LDhard
- referencedirectory_tmpl: a template for path to the folder containing Event files (.mat files in SPM-format)
- Required format:
must contain "*" which will be substituted withID (see above)
- E.g.: '/imaging/ta02/ActionWords/Analysis/E-Prime/DAW*/ref'
The folder should contain the regressor(s) in SPM format (.mat file) with filename format: condition_vol_ID-Session Name.mat.
- E.g. (based on the example above): condition_vol_2-LDeasy.mat
- Required format:
- Then you add these lines to your UMS (based on the example above):
aap.acq_details.input.list='/imaging/ta02/ActionWords/Analysis/Subject_List_Test.csv'; aap.acq_details.input.selected_sessions = [3 4]; aap.acq_details.input.referencedirectory_tmpl = '/imaging/ta02/ActionWords/Analysis/E-Prime/DAW*/ref'; aap = aas_processinput(aap);
Recent Updates
2013/08/08 Parallel computing is working
- To enable parallel computing you have to be logged in an appropriate computing machine (login11-14) and add the following line to your UMS:
aap.options.wheretoprocess = 'qsub'; % parallel; typical localsingle
Known bugs:
Conventional SPM diagnostic will be missing for:
- aamod_realignunwarp (only fieldmaps)
- aamod_coreg_noss
However, FSL diagnostics are unaffected.
2013/08/02 new version v4.1 (latest devel-share branch from GitHub)
merge with GitHub completed
- release-4.1 is now the latest stable
2013/06/26 merge with the latest devel-rhodri branch from GitHub
- release-4.0 is now the latest stable
2013/06/06 new feature
NIFTI-4D support added. It works only with spm8_fil_r5236
- As a default, NIFTI-3D is set. To enable NIFTI-4D, you have to specify it in the UMS:
aap.options.NIFTI4D = 1; % 4D support; typical value 0
2013/05/13 new feature
- Garbage collection tested
- New report summary:
- Head movement: outlier-detection with boxplot
2013/04/24 CBSU Patch/Extension for Version 4 is available
New features:
- Handling input file as a list of subjects and sessions (see Advanced Features/Input file)
- Module for first-level thresholding
- List of significant activation maps
- Overlays on axial slices (T1 MNI)
- Rendering results in 3D
- Multi-level interlinked reporting:
- Study (reporting second-level)
- Subjects (each subjects separately)
- Summaries:
- Subjects
- Registration
- First-level thresholded maps
Known bugs:
Parallel computing is still not working!
