The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.
ExoW3-NLDM
54 LCMS runs (mzML). Every file is self-describing: the complete experimental record is encoded directly into the mass spectra with SpectraCodec. Decode any single file to recover it. How the encoding and decoding works is documented in the SpectraCodec repository.
Authenticity
Every file is cryptographically signed. The embedded message carries a
provenance block with two Ed25519 signatures: payload_signature covers the
embedded experimental record, and spectra_signature covers the acquired
spectra themselves (via a spectral digest that excludes the carrier spectrum).
