Getting Started

A step-by-step tutorial is provided in the following sections.

Prerequisites

You should install CUDA-enabled GPU cards with at least 8GB GPU memory manufactured by nVidia, e.g., Titan XP.

Prepare T1-weighted MR images

1. Convert MR images to Neuroimaging Informatics Technology Initiative (NIfTI) format.
2. The parent directory name of a NIfTI file path will be used as Subject Id during prediction.
3. You can specify either an input path of the NIfTI file or input direcotry of many NIfTI files.

Install DeepParcellation

1. Install Anaconda
   • Download an Anaconda distribution: Link
2. Create a Conda environment

	conda create -n deepparc python=3.8 -y

3. Install DeepParcellation (CPU mode)

	conda activate deepparc
	pip install deepparcellation

4. Install DeepParcellation (GPU mode)

	conda activate deepparc
	pip install deepparcellation
	conda install cudnn=7.6.5 -c anaconda -y
	conda install cudatoolkit=10.1.243 -c conda-forge -y
	pip uninstall tensorflow -y
	pip install tensorflow-gpu==2.2.0
	pip uninstall keras -y
	conda install keras-gpu=2.4.3 -c anaconda -y

5. Install DeepParcellation (Mac with M1 Chip)

	conda activate deepparc
	export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1
	export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
	export CFLAGS="-I/opt/homebrew/opt/openssl/include"
	export LDFLAGS="-L/opt/homebrew/opt/openssl/lib"
	conda install -c apple tensorflow-deps -y
	pip install tensorflow-macos
	pip install deepparcellation

6. Run DeepParcellation

	conda activate deepparc
	deepparcellation -o=/tmp/test --i=./subject-0-0000/test.nii.gz
	or
	deepparcellation -o=/tmp/test --i=./

NOTE:

1. You must always activate the conda enviroment before running DeepParcellation if you opened a new console.
