+# WSI_Embedding
+
+Patch and slide embeddings for whole-slide images, plus the run records used to produce them.
+
+**Original WSIs are not in this repo.** They stay on HPC / the source dataset remotes. Do not expect `.svs` / `.tif` here.
+
+Repo: [`thanminh01/WSI_Embedding`](https://huggingface.co/datasets/thanminh01/WSI_Embedding)
+
+## Top-level layout
+
+| Path | What it is | Download when |
+|---|---|---|
+| `embeddings/<dataset>/<model>/<mag>x_<patch>px_<overlap>px_overlap/` | Encoder tensors (`.h5` / `.pt` / WSI-LLaVA json) and per-model TRIDENT `_config_` / `_logs_` | You need features |
+| `Run-Information/runs-report/<dataset>/` | Job logs, VALIDATION, SLURM, perf, TRIDENT `runs/*.json`, cohort CSVs | You need provenance |
+| `Run-Information/prep/<dataset>/` | Contours, geojson, thumbnails, `wsi_states`, patch-coord h5 `(N,2)`, overlay jpgs | You need QC / failed-mask / tiny-slide evidence |
+| `Run-Information/parked/<dataset>/` | Encoder files for slides excluded from the official cohort | You need the parked cases |
+
+Selective download: pull only `embeddings/DHMC-LUAD/titan/...` or only `Run-Information/prep/TCGA-LUAD`.
+
+## Datasets
+
+### DHMC-LUAD (encoder cohort 143)
+
+There are **two HPC job directories**. They are **not** duplicates of the same run:
+
+| Hub name | HPC folder | Role |
+|---|---|---|
+| `DHMC-LUAD` | `runs-information/full-int-DHMC-LUAD/` | Canonical shared coords + later encoders (Virchow/PRISM/KEEP/MUSK/WSI-LLaVA/PRISM2, MUSK 1024-d redo) |
+| `DHMC-LUAD-TITAN-CONCH` | `runs-information/full-int-DHMC-LUAD (TITAN CONCH)/` | First encoder pack: TITAN + CONCH v1.5 / v1 at 20×/512 |
+
+Use `DHMC-LUAD` for current coords, masks, and later-model logs. Use `DHMC-LUAD-TITAN-CONCH` for the original TITAN/CONCH job (SLURM 15450381 / 15450382).
+
+Kept encoders (see per-model folders under `embeddings/DHMC-LUAD/`): TITAN 768, CONCH v1.5 768, CONCH v1 512, Virchow 2560, PRISM 1280, Virchow2 2560, Virchow2 CLS 1280, PRISM2, KEEP 768, MUSK **1024-d vision CLS** (`ms_aug=False`, no CLIP head in the stored tensor), WSI-LLaVA captions + case-bank. GigaPath tiles at 512 exist only as the WSI-LLaVA tile encoder, not as an official GigaPath product.
+
+### TCGA-LUAD (encoder cohort 531)
+
+531 diagnostic slides after parking **10 TCGA-05 DX1** cases (tiny GDC canvas + failed tissue mask). Those 10 are **not** in `embeddings/` tensors (except leftovers under `parked/`). Their `wsi_states`, thumbnails, contours, and coords **are** in `Run-Information/prep/TCGA-LUAD/` so the failure stays inspectable.
+
+Tensors for TCGA-LUAD may still be landing on HPC; this `Run-Information` tree is uploaded independently.
+
+### TCGA-LUSC
+
+Not in this `Run-Information` snapshot: prep was still writing on the cluster at upload time. Encoder tensors are not published yet.
+
+## Canonical mag / patch
+
+| Models | Setting |
+|---|---|
+| TITAN, CONCH v1.5, CONCH v1, WSI-LLaVA | 20× / 512 |
+| PRISM, Virchow, Virchow2, Virchow2 CLS, PRISM2 | 20× / 224 |
+| KEEP | 20× / 256 |
+| MUSK | 20× / 384 |

+## How to download
+
+```bash
+# tensors only, one model
+huggingface-cli download thanminh01/WSI_Embedding \
+  --repo-type dataset \
+  --include "embeddings/DHMC-LUAD/titan/**"
+
+# QC / logs only
+huggingface-cli download thanminh01/WSI_Embedding \
+  --repo-type dataset \
+  --include "Run-Information/**"
+```
+
+## What is intentionally absent
+
+- Original whole-slide images
+- HPC `runs-information/full-int-*/features_*` trees (those tensors live under `embeddings/` so they are not uploaded twice)
+- `TCGA-LUSC` run snapshot while segmentation/coords were still in flight
