+# Dataset, model weight, source code for paper "HistGen: Histopathology Report Generation via Local-Global Feature Encoding and Cross-modal Context Interaction"
+
+## Prerequisite
+Follow this instruction to create conda environment and install necessary packages:
+```
+git clone https://github.com/dddavid4real/HistGen.git
+cd HistGen
+conda env create -f requirements.yml
+```
+## HistGen WSI-report dataset
+Our curated dataset could be downloaded from <https://hkustconnect-my.sharepoint.com/:f:/g/personal/zguobc_connect_ust_hk/EhmtBBT0n2lKtiCQt97eqcEBWnB6K9-Dwr3wruaLyd_xTQ?e=IdWZmi>.
+
+The structure of this fold is shown as follows:
+```
+HistGen WSI-report dataset/
+|-- WSIs
+|    |-- slide_1.svs
+|    |-- slide_2.svs
+|    ╵-- ...
+|-- dinov2_vitl
+|        |-- slide_1.pt
+|        |-- slide_2.pt
+|        ╵-- ...
+╵-- annotation.json
+```
+in which **WSIs** denotes the original WSI data from TCGA, **dinov2_vitl** is the features of original WSIs extracted by our pre-trained DINOv2 ViT-L backbone, and **annotation.json** contains the diagnostic reports and case ids of their corresponding WSIs. Concretely, the structure of this file is like this:
+```
+{
+    "train": [
+        {
+            "id": "TCGA-A7-A6VW-01Z-00-DX1.1BC4790C-DB45-4A3D-9C97-92C92C03FF60",
+            "report": "Final Surgical Pathology Report Procedure: Diagnosis A. Sentinel lymph node, left axilla ...",
+            "image_path": [
+                "/storage/Pathology/wsi-report/wsi/TCGA-A7-A6VW-01Z-00-DX1.1BC4790C-DB45-4A3D-9C97-92C92C03FF60.pt"
+            ],
+            "split": "train"
+        },
+        ...
+    ],
+
+    "val": [
+        {
+            "id": "...",
+            "report": "...",
+            "image_path": ["..."],
+            "split": "val"
+        },
+        ...
+    ],
+
+    "test": [
+        {
+            "id": "...",
+            "report": "...",
+            "image_path": ["..."],
+            "split": "test"
+        },
+        ...
+    ]
+}
+```
+in which we have already split into train/val/test subsets with ratio 8:1:1. Besides, "id" denotes the case id of this report's corresponding WSI, "report" is the full refined text obtained after our proposed report cleaning pipeline, and "image_path" could be just ignored. 
+
+<!-- Note that before you use this json file for training, please run the `replace_pt_path.py` we provided to change the "image_path". Usage of `replace_pt_path.py` is written inside the python file. -->
+
+## Pre-trained DINOv2 ViT-L Feature Extractor
+We are organizing the training details, dataset used, and other information to release the pre-trained model. Please stay tuned for the update.
+
+## HistGen WSI Report Generation Model
+To try our model for training, validation, and testing, simply run the following commands:
+```
+cd HistGen
+conda activate histgen
+sh train_wsi_report.sh
+```
+Before you run the script, please set the path and other hyperparameters in `train_wsi_report.sh`.
