cellshape-voxel 0.0.4rc0

3D shape analysis using deep learning

---

Cellshape-voxel is an easy-to-use tool to analyse the shapes of cells using deep learning and, in particular, 3D convolutional neural networks. The tool provides the ability to train 3D convolutional autoencoders on 3D single cell masks as well as providing pre-trained networks for inference.

To install

pip install cellshape-voxel

                         resnet_shortcut_type="B",
                         resnet_widen_factor=1.0)

volume = torch.randn(1, 64, 64, 64, 1)

recon, features = model(volume)

Parameters

• num_features: int.
  The size of the latent space of the autoencoder. If you have rectangular images, make sure your image size is the maximum of the width and height
• k: int.
  The number of neightbours to use in the k-nearest-neighbours graph construction.
• encoder_type: int.
  The type of encoder: 'foldingnet' or 'dgcnn'
• decoder_type: int.
  The type of decoder: 'foldingnet' or 'dgcnn'

For developers

• Fork the repository
• Clone your fork

git clone https://github.com/USERNAME/cellshape-voxel 

• Install an editable version (-e) with the development requirements (dev)

cd cellshape-voxel
pip install -e .[dev] 

• To install pre-commit hooks to ensure formatting is correct:

pre-commit install

• To release a new version:

Firstly, update the version with bump2version (bump2version patch, bump2version minor or bump2version major). This will increment the package version (to a release candidate - e.g. 0.0.1rc0) and tag the commit. Push this tag to GitHub to run the deployment workflow:

git push --follow-tags

Once the release candidate has been tested, the release version can be created with:

bump2version release
