During this session, we will demonstrate how to perform a sulcal morphometry study for a set of T1 MRI images, using BrainVisa and especially its Morphologist toolbox.
The Morphologist pipeline will perform all preprocessings: brain alignment, brain extraction, tissues classification, cortical folds detection, structured representation of sulci, sulci identification, morphometric features extraction in a data table.
Users are then free tu use their favorite statistical or machine learning package to perform classification, regression, or correlation studies on populations.
The session will include manipulation of the main Morphologist pipeline, and some tools around, including 3D visualization, in order to show how users can operate more custom processing.
As it is a "hands-on" session, attending people are expected to come with a laptop with the BrainVISA distribution installed (https://brainvisa.info), and they may bring a small set of T1 MRI images to process. 3D Visualization demos will include data from the BigBrain image, preprocessed using Morphologist.
Denis Riviere has been working in research on brain sulcal anatomy and on related analysis methods since 1996, still in the same group now in NeuroSpin (France). He has been one of the main developers and maintainers of the BrainVISA, Anatomist, AIMS software suite and the Morphologist toolbox, and is still involved in research in sulcal patterns data mining, using image processing, and machine learning methods.
Jean-François Mangin is the head of the methodological research unit of Neurospin, and the head of the French platform for multicenter neuroimaging (CATI). He has been one of the deputies of Katrin Amunts in the HBP. His main research program aims at deciphering the variability of the cortical folding pattern.
