| # 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](https://github.com/XinhengLyu/WSI-LLaVA) and the |
| [SlideChat](https://github.com/uni-medical/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](https://github.com/uni-medical/SlideChat/tree/main/dataset) |
| and [BCNB](https://bupt-ai-cz.github.io/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](https://huggingface.co/MahmoodLab/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. |
