+This repository provides source code and pre-trained models for brain tumor segmentation with BraTS dataset. The method is detailed in [1], and it won the 2nd place of MICCAI 2017 BraTS Challenge. In addition, it is adapted to deal with BraTS 2015 dataset.
 
 This implementation is based on NiftyNet and Tensorflow. While NiftyNet provides more automatic pipelines for dataloading, training, testing and evaluation, this naive implementation only makes use of NiftyNet for network definition, so that it is lightweight and extensible. A demo that makes more use of NiftyNet for brain tumor segmentation is proivde at

-* BraTS dataset. Data can be downloaded from http://braintumorsegmentation.org/
+* BraTS 2015 or 2017 dataset. Data can be downloaded from http://braintumorsegmentation.org/
 
 # How to use
 ## 1, Prepare data
-* Download BraTS dataset, and uncompress the file to `./data` folder. For example, the training set will be in `./data/Brats17TrainingData` and the validation set will be in `./data/Brats17ValidationData`.
+* Download BraTS dataset, and uncompress the training and tesing zip files. For example, the training set will be in `data_root/BRATS2015_Training` or `data_root/Brats17TrainingData` and the validation set will be in `data_root/BRATS2015_Validation`.
 
-* Process the data. Run:
-
-```bash 
-python pre_process.py
-```
-
-## 2, Use pre-trained models
-* Download pre-trained models from https://drive.google.com/open?id=1moxSHiX1oaUW66h-Sd1iwaTuxfI-YlBA, and save these files in `./model_pretrain`.
-* Obtain binary segmentation of whole tumors, run:

 ## 3, How to train
 The trainig process needs 9 steps, with axial view, sagittal view, coronal view for whole tumor, tumor core, and enhancing core, respectively.
 
-The following commands are examples for these steps. However, you can edit the corresponding `*.txt` files for different configurations.

+
+* To save the time for training, you may use the modals in axial view as initalizations for sagittal and coronal views. Copy variales in axial view to those in sagittal or coronal view by running:
+```bash
+python util/rename_variables.py
 ```
+You may need to edit this file to set different parameters. As an example for Brats 2015, after running this command, you will see a model named `model15/msnet_tc32sg_init` that is copied from `model15/msnet_tc32_20000.ckpt`. Then just set `start_iteration=1` and `model_pre_trained=model15/msnet_tc32sg_init` in `config15/train_tc_sg.txt`.
