# Pan-Cancer Histology Dataset for Nuclei Instance Segmentation and Classification (PanNuke) | ||
|
||
## Description | ||
|
||
This project supports **`Pan-Cancer Histology Dataset for Nuclei Instance Segmentation and Classification (PanNuke)`**, which can be downloaded from [here](https://academictorrents.com/details/99f2c7b57b95500711e33f2ee4d14c9fd7c7366c). | ||
|
||
### Dataset Overview | ||
|
||
Semi automatically generated nuclei instance segmentation and classification dataset with exhaustive nuclei labels across 19 different tissue types. The dataset consists of 481 visual fields, of which 312 are randomly sampled from more than 20K whole slide images at different magnifications, from multiple data sources. In total the dataset contains 205,343 labeled nuclei, each with an instance segmentation mask. Models trained on pannuke can aid in whole slide image tissue type segmentation, and generalise to new tissues. PanNuke demonstrates one of the first successfully semi-automatically generated datasets. | ||

### Dataset Citation | ||
|
||
``` | ||
@inproceedings{gamper2019pannuke, | ||
title={PanNuke: an open pan-cancer histology dataset for nuclei instance segmentation and classification}, | ||
author={Gamper, Jevgenij and Koohbanani, Navid Alemi and Benet, Ksenija and Khuram, Ali and Rajpoot, Nasir}, | ||
booktitle={European Congress on Digital Pathology}, | ||
pages={11--19}, | ||
year={2019}, | ||
} | ||
``` | ||
|
||
### Prerequisites | ||
|
||
- Python v3.8 | ||
- PyTorch v1.10.0 | ||
- pillow(PIL) v9.3.0 9.3.0 | ||
- scikit-learn(sklearn) v1.2.0 1.2.0 | ||
- [MIM](https://github.com/open-mmlab/mim) v0.3.4 | ||
- [MMCV](https://github.com/open-mmlab/mmcv) v2.0.0rc4 | ||
- [MMEngine](https://github.com/open-mmlab/mmengine) v0.2.0 or higher | ||
- [MMSegmentation](https://github.com/open-mmlab/mmsegmentation) v1.0.0rc5 | ||
|
||
All the commands below rely on the correct configuration of `PYTHONPATH`, which should point to the project's directory so that Python can locate the module files. In `pannuke/` root directory, run the following line to add the current directory to `PYTHONPATH`: | ||
|
||
```shell | ||
export PYTHONPATH=`pwd`:$PYTHONPATH | ||
``` | ||
|
||
### Dataset Preparing | ||
|
||
- download dataset from [here](https://academictorrents.com/details/99f2c7b57b95500711e33f2ee4d14c9fd7c7366c) and decompress data to path `'data/'`. | ||
- run script `"python tools/prepare_dataset.py"` to format data and change folder structure as below. | ||
- run script `"python ../../tools/split_seg_dataset.py"` to split dataset and generate `train.txt`, `val.txt` and `test.txt`. If the label of official validation set and test set cannot be obtained, we generate `train.txt` and `val.txt` from the training set randomly. | ||

### Training commands | ||
|
||
To train models on a single server with one GPU. (default) | ||
|
||
```shell | ||
mim train mmseg ./configs/${CONFIG_FILE} | ||
``` | ||
|
||
### Testing commands | ||
|
||
To test models on a single server with one GPU. (default) | ||

mim test mmseg ./configs/${CONFIG_FILE} --checkpoint ${CHECKPOINT_PATH} | ||
``` | ||
|
||
<!-- List the results as usually done in other model's README. [Example](https://github.com/open-mmlab/mmsegmentation/tree/dev-1.x/configs/fcn#results-and-models) | ||
You should claim whether this is based on the pre-trained weights, which are converted from the official release; or it's a reproduced result obtained from retraining the model in this project. --> | ||
