Sources and terms
This repository distributes pre-extracted numeric features, matching coordinates, and processed training/evaluation annotation JSON. It does not distribute raw whole-slide images, image patches, original pathology reports, report PDFs, model weights, or original clinical tables.
Annotation and split provenance
Training and WSI-Bench evaluation annotations are adapted from
WSI-LLaVA / WSI-Bench and the
SlideChat data preparation used by
LoC-Path. The task partitions are inherited from WSI-LLaVA/WSI-Bench through that
preparation; this release does not introduce a new split. Image references are
normalized into feature lookup stubs, machine-specific feature paths are removed,
and records lacking corresponding released features are omitted. Counts and
omissions are recorded in metadata/dataset_summary.json and
metadata/excluded_records.json.
BCNB evaluation annotations and feature CSVs are adapted from the SlideChat data release. See its dataset documentation and BCNB.
Feature provenance
TCGA feature arrays were previously extracted from TCGA slides with CONCH v1. Features have 512 columns; feature/coordinate row order is retained. Existing NPY arrays are published without a precision conversion. BCNB CSV features are the 512-dimensional CONCH features supplied with SlideChat and include patch coordinate names, not patch image contents.
CONCH is supplied by MahmoodLab under its own model terms, including noncommercial research restrictions. Those terms also address commercial use of datasets derived from CONCH. Consult the source terms for your intended use. CONCH weights are not included here.
Rights and attribution
The LoC-Path code license does not relicense TCGA, BCNB, WSI-Bench, SlideChat, or CONCH assets. This collection is provided subject to applicable source-data and model terms; no blanket permissive data license is granted. Cite the corresponding data, annotation, and feature-extractor sources when using this collection. Raw TCGA assets must be obtained through their original access channels and are not part of this release.
