CAT12 is an extension to SPM12 (Wellcome Department of Cognitive Neurology) to provide computational anatomy. This covers diverse morphometric methods such as voxel-based morphometry (VBM), surface-based morphometry (SBM), deformation-based morphometry (DBM), and region- or label-based morphometry (RBM).
It is developed by Christian Gaser and Robert Dahnke.
Detailed instructions for download and installation can be found here.
You can download the CAT12 manual here.
A good starting point for using CAT12 is the Quick Start Guide.
Please cite our papers and the work of other researchers if you use this software.
These protocols use CAT12 to process voxel- and surface-based morphometry, but also enable region-based measures for volume and surface data.

This toolbox is an extension to SPM12 (Wellcome Department of Cognitive Neurology) to provide non-parametric statistics based on threshold-free cluster enhancement (TFCE). It is developed by Christian Gaser.
You can start the toolbox by choosing "TFCE" in the "Toolbox" selector.
The toolbox is an open source toolbox for SPM12 that is able to segment T2 hyperintense lesions in FLAIR images. Originally developed for the segmentation of MS lesions it has has also been proven to be useful for the segmentation of brain lesions in the context of other diseases, such as diabetes mellitus or Alzheimer's disease.
Currently, there are two algorithms implemented for lesion segmentation. The first, a lesion growth algorithm (LGA, Schmidt et al., 2012), requires a T1 image in addition to the FLAIR image. The second algorithm, a lesion prediction algorithm (LPA, Schmidt, 2017, Chapter 6.1), requires a FLAIR image only. As a third highlight a pipeline allowing the longitudinal segmentation (Schmidt et al., 2019) is implemented. In addition, the toolbox can be used to fill lesions in any image modility.
The toolbox was developed by a collaboration of the following organizations: Morphometry Group, Department of Neurology, Technische Universität München (TUM), Munich, Department of Statistics, Ludwig-Maximilians-University, Munich, Germany, and Structural Brain Mapping Group, Departments of Neurology and Psychiatry, Friedrich-Schiller-University, Jena, Germany. The rationale, approach and further details are available in a NeuroImage paper.
We make the software available at the website of Paul Schmidt.
You can start the toolbox by choosing "LST" in the "Toolbox" selector.
The TOM toolbox takes a radically new approach towards providing reference data, based on imaging data from the NIH study of normal brain development. Using the general linear model, we statistically isolate the influence of external variables of interest on brain structure, allowing us to generate high-quality matched templates for any given group of subjects. The toolbox offers two options:
Of note, this approach is generally applicable and in no way restricted to analyzing pediatric imaging data: for example, if you aim at investigating the effects of aging in elderly subjects, the toolbox will also allow you to create more appropriate reference (if your group is large enough to isolate such effects).
Two general approaches seem feasible to construct appropriate reference data. First, the average age, gender, etc. is calculated based on the supplied input information (i.e., the demographic variables of the sample under study), and a fitting average template is created accordingly. Here, we term this the average approach. Alternatively, the input sample could be completely matched such that one reference tissue map is generated for each input subject, and these matched reference maps would only be averaged at the end. We term this the matched pairs approach.
For all template files we also save the according mat-file. Although, this is non-standard for nifti-images, it will offer backwards compatibility to older SPM versions. SPM5 (and all other nifti-based software) will simply ignore the mat-file.
Age can be modeled as polynomial regression with up to third order terms. The simplest model is a linear regression (which is not recommended). Either third or second order regression is appropriate for modeling aging effects. The different age terms will be orthogonalized with regard to its
This toolbox is the result of a joint effort by the Department of Pediatric Neurology and Developmental Medicine (Marko Wilke, Tuebingen, Germany), the Imaging Research Center (Scott Holland and Mekibib Altaye, Cincinnati, OH, USA), and the Structural Brain Mapping Group (Christian Gaser, Jena, Germany). The rationale, approach and further details are available in a NeuroImage paper.
You can start the toolbox by choosing "TOM" in the "Toolbox" selector.
The VBM toolboxes are a collection of extensions to the segmentation algorithm of SPM2, SPM5, and SPM8 (Wellcome Department of Cognitive Neurology) to provide voxel-based morphometry (VBM). The toolboxes are named according to the SPM version. It is developed by Christian Gaser.
Please note, that CAT12 replaces these earlier toolboxes. It contains significant improvements over VBM8 and the main difference (other than running under SPM12) is the ability to estimate and analyze cortical surface and associated parameters such as thickness and gyrification. This important change is now reflected in the name of the new toolbox, as CAT12 will provide easy-to-use tools covering different morphometric methods such as voxel-based morphometry (VBM), surface-based morphometry (SBM), deformation-based morphometry (DBM), and region- or label-based morphometry (RBM).
You can start the toolbox by choosing "vbm8" in the "Toolbox" selector.
A manual can be found here VBM8-Manual (written by Florian Kurth and Eileen Lüders).
You can start the toolbox by choosing "vbm5" in the "Toolbox" selector.
A preliminary manual can be found here VBM5.1-Manual.
Unpack the zip-file. Now, you have two options for using VBM2 within SPM:
First (and recommended), you can copy or link the vbm2 folder to the spm2/toolbox directory. You can start the toolbox by selecting "vbm2" from the toolbox button on the SPM interface after restarting spm.
Secondly, you can add the vbm2 folder to your matlab path and can start from the matlab prompt with the command "spm_vbm2".
