NEMAR
Archive, share, and process BIDS neurophysiology datasets. Start with the CLI; the rest of the platform is documented here too.
What is NEMAR?
Section titled “What is NEMAR?”NEMAR (Neuroelectromagnetic Data Archive and Tools Resource) is a platform for archiving, sharing, and processing neuroimaging datasets in Brain Imaging Data Structure (BIDS) format. It is several systems working together: a website, a CLI, a backend API, a Zarr serving copy for signal data, and a Model Context Protocol (MCP) server for AI assistants. If you are not sure which of those you want, start with Which surface should I use?.
Why use NEMAR? See what NEMAR adds around a citable dataset: metadata, versioning, APIs, the CLI, and derived access.
Which surface should I use? The website, the CLI, the API, the Zarr copy, or the MCP server: what each is for, and why not the others.
The NEMAR ecosystem How the CLI, APIs, data plane, browser, and viewer fit together.
CLI Upload, validate, version, and download datasets from your terminal.
Platform & APIs The backend API and the public data plane.
MCP server Tool calling for AI assistants and agents: six tools at mcp.nemar.org, no account and no install.
Admin Operations and runbooks for NEMAR administrators (access-gated).
