Note that for most other Brainstorm use cases (e.g. Here we illustrate only the use of Brain2mesh: this is not the most accurate solution for MRI segmentation but it is probably the fastest option to obtain a tetrahedral mesh of the head with 5 tissues (gray matter, white matter, CSF, skull, skin). The methods available within Brainstorm are listed in the tutorial FEM mesh generation. The FEM approach requires a segmentation of the head volume in different tissues, represented as hexahedral or tetrahedral 3D meshes. From 1 to 9: components of the three eigenvectors from 10 to 12: the values of their norm to the eigenvalue. At the end, a new file DTI-EIG appears in the database (DTI=diffusion tensors images, EIG=eigenvalue). If you don't have them, ask the person who programmed your DWI sequence and get the files that are specific to your use case. Theses files are created from for the DWI acquisition.

The associated text files *.bvec (orientation of the gradient) and *.bval (value of the gradient) must be in the same folder, with the same file name. Right-click on Subject01 > Convert DWI to DTI This computes the This requires BrainSuite to be installed on your computer, with the bdp program available in the system path. The NAS/LPA/RPA fiducials are needed for defining the Brainstorm subject coordinate system, in which the surfaces and FEM meshes are stored. This estimates an affine transformation to the MNI space and sets default positions for the anatomical fiducials.

You will be using BrainSuite Diffusion Pipeline (BDP), so you need to install a compatible MATLAB Runtime (2019b for BrainSuite 21a). Install it on your computer by following the instructions in BrainSuite's quick start installation guide. For the DWI data, only the NIfTI files (.nii) are supported.ĭownload the latest version of BrainSuite from.You have a working copy of Brainstorm installed on your computer.You have already followed all the introduction tutorials.
