libspatialindex provides spatial indexing utilities, with support for sophisticated spatial queries and interfaces for updating information and customizing the storage management of indices. The library is written in C++, with a C API.

The purpose of the GMlib is to provide programmers of solvers or automated meshers in the field of scientific computing with an easy, fast and transparent way to port their codes on GPUs (Graphic Processing Units).

This library is based on the OpenCL language standard, thus taking advantage of almost every architectures supported by most platforms (Linux, macOS, Windows).

It is a simple loop parallelization scheme (known as kernels in the realm of GPU computing), provides the programer with pre defined mesh data structures, automatically vectorizes unstructured data like the ball of points or the edge shells, and handles transparently the transfer and vectorization of mesh data structures.

This package provides a hash table library that offers dynamicaly resizing tables and arbitrary number of hash keys insert and queries.

The Gamma Mesh Format (GMF) and the associated library libMeshb provide programers of simulation and meshing software with an easy way to store their meshes and physical solutions. The GMF features more than 200 kinds of data types, like vertex, polyhedron, normal vector or vector solution field. The libMeshb provides a convenient way to move data between those files, via keyword tags, and the user's own structures.

The purpose of the LPlib is to provide programmers of solvers or automated meshers in the field of scientific computing with an easy, fast and transparent way to parallelize their codes. This library is based on posix standard threads, also known as pthreads, thus taking advantage of multi-core chips and shared memory architectures supported by most platforms (Linux, macOS, Windows).

Version 4 provides an early implementation of colored grains scheduling for better scaling and memory localization with high core count systems.

The libOL first store a mesh made of vertices, edges and triangles in an octree structure with a very small memory footprint. Subsequently, you can perform geometrical queries very quickly on this mesh:

• retrieve the closest entity from a given set of coordinates

• build the list of mesh entities than are include in a given bounding box

• project a vertex on any kind of geometrical entity

• launch a ray and get the first intersected entity

• all query operations can be performed in parallel as the library is thread safe

libsupermesh is a Fortran 2008 library to intersect two overlapping meshes element by element. Pairs of overlapping elements are identified and a local mesh of their intersection is generated.

MVAPICH2 (pronounced as “em-vah-pich 2”) is an open-source MPI software to exploit the novel features and mechanisms of high-performance networking technologies (InfiniBand, iWARP, RDMA over Converged Enhanced Ethernet (RoCE v1 and v2), Slingshot 10, and Rockport Networks) and deliver best performance and scalability to MPI applications.

This package contains the binary resulting from the compilation of hello_c.c in the examples subdirectory of the Open MPI source code. It can be used to check MPI connectivity on a machine/cluster.

MVAPICH (pronounced as “em-vah-pich”) is an open-source MPI software to exploit the novel features and mechanisms of high-performance networking technologies (InfiniBand, iWARP, RDMA over Converged Enhanced Ethernet (RoCE v1 and v2), Slingshot 10, and Rockport Networks) and deliver best performance and scalability to MPI applications. MVAPICH 4.1 has support for the Cray Slingshot 11, Cornelis OPX, and Intel PSM3 interconnects through the OFI libfabric library, and for the UCX communication library.

Umpire is a resource management library that allows the discovery, provision, and management of memory on machines with multiple memory devices like NUMA and GPUs.

MRtrix3 provides a large suite of tools for image processing, analysis and visualisation, with a focus on the analysis of white matter using diffusion-weighted MRI.

fsleyes_props is a framework for event-driven programming using Python descriptors, similar in functionality to, and influenced by Enthought Traits.

This package provides utilities for feature analysis, preprocessing and visualization of image quality metrics generated by MRIQC.

Convert data from DICOM and organise the resulting NIfTI files into BIDS.

The fslpy package is a collection of utilities and data abstractions used within FSL and by FSLeyes.

heudiconv is a flexible DICOM converter for organizing brain imaging data into structured directory layouts.

This package provides Python tools for working with the BIDS schema.

FSL is a comprehensive library of analysis tools for FMRI, MRI and diffusion brain imaging data. FSLeyes is a GUI for visualizing and editing brain images, from different sources and platforms.

A Python implementation of the moving average principal components analysis methods for functional MRI data translated from the MATLAB-based GIFT package.

NARPS Open Pipelines is a project aimed at reproducing the 70 pipelines from the NARPS study (Botvinik-Nezer et al., 2020) and sharing them as an open resource for the community. It uses Nipype for workflow management and provides templates to facilitate the reproduction of neuroimaging analyses.

This package provides the Python Client code for accessing neuroimaging templates hosted using TemplateFlow.

This package provides programs to perform EM based segmentation of images in nifti or analyse format.

NeuroImaging Workflows provides processing tools for magnetic resonance images of the brain.
