Software

MeCA develops various types of methods for data analysis and we dedicate a lot of time to make sure these methods are freely available in software packages:

  •   the Cortical Surface toolbox that comes included in the official BrainVisa distribution and provides many methods for cortical surface analyses. See below for details.
  • the Diffuse toolbox that can be installed on top of BrainVisa and provides diffusion MR data management as well as an easy access to a full set of dMRI analysis method provided by FSL and DiPy. Diffuse is available on its github page.
  • The SLAM python module that provides methods for analysing and modeling surfaces represented as a triangular mesh. SLAM development is led by G. Auzias.
  • Kep Kee Loh also contributed to the MacaPype pipeline, a NiPype extension that provides methods for non-human primate anatomical MRI segmentation.

Below you can find some information and documentation about some of our modules and pipelines. Documentation and tutorials are also available and will be added over time in order to show how to use pipelines and what to do with them.

Most of our BrainVisa pipelines need the Morphologist Pipeline to be run beforehand, in order to have triangular meshes of the cortical surface and all sulci, as well as a labelling of these sulci.

People who have contributed to the toolboxes and software of the team are: Guillaume Auzias, Olivier Coulon, Grégory Operto, Arnaud LeTroter, Denis Rivière, Cédric Clouchoux, Alexandre Pron, Lucile Brun, Julien Lefèvre, Kep Kee Loh.

Brainvisa tutorials

Below are links to the slides of three BrainVisa tutorials that were given at INT. They provide help for using BrainVisa, from basic use to producing MarsAtlas from a T1 image. BrainVisa: basic concepts, setting up a database, importing a T1 image, iterating over several subjects. Morphologist 2015: from T1 image to sulcal recognition. The …

Hip Hop

Cortical surface parameterization and inter-subject matching This process performs a parametrization of the white matter surface, and implicitely provides an inter-subject cortical surface matching. The resulting 2D coordinate system (longitude/latitude) is fitted to a model of cortical organization, which means that a number of sulcal lines have a constant coordinate (longitude or latitude) and that …

HipHop138

Cortical Surface group template DOWNLOAD In order to have a reference surface for group studies, we built a surface template of the cortical surface. The HipHop138 template has been built by averaging the surfaces of 138 subjects after running the HipHop surface parameterization on these subjects. Both hemispheres have been processed separately.   HipHop138 is …

MarsAtlas

Cortical parcellation model MarsAtlas is a model of cortical parcellation. It can be applied to any cortical surface via the HipHop parameterization pipeline, available in the BrainVisa Cortical Surface Toolbox, under the Anatomy category. MarsAtlas has been developed in collaboration with Andréa Brovelli at INT. It has been primarily designed for functional data analysis and …

Slam

    SLAM is an open source python package dedicated to the representation of neuroanatomical surfaces stemming from MRI data in the form of triangular meshes, and to their processing and analysis. The development of slam is led by G. Auzias. The SLAM website is here, and the code is available on its github repository: …

Sulcal parameterization

This process performs a length-parameterization of  sulcus meshes. This is useful to study the morphology of sulci and localize features on them. The sulcus needs to have been identified and labelled automatically or by hand before, and is modeled by a triangular mesh. The result is a coordinate field that localize any point on the …
