Deep Learning Methods for Parsing T-Cell Receptor Sequencing (TCRSeq) Data

Project description

DeepTCR

Deep Learning Methods for Parsing T-Cell Receptor Sequencing (TCRSeq) Data

DeepTCR is a python package that has a collection of unsupervised and supervised deep learning methods to parse TCRSeq data. To see examples of how the algorithms can be used on an example datasets, see the subdirectory 'tutorials' for a collection of tutorial use cases across multiple datasets. For complete documentation for all available methods, see 'Documentation.txt'.

While DeepTCR will run with Tensorflow-CPU versions, for optimal training times, we suggest training these algorithms on GPU's (requiring CUDA, cuDNN, and tensorflow-GPU).

DeepTCR now has the added functionality of being able to analyze paired alpha/beta chain inputs as well as also being able to take in v/d/j gene usage and the contextual HLA information the TCR-Sequences were seen in (i.e. HLA alleles for a repertoire from a given human sample). For detailed instructions on how to upload this type of data, refer to the documentation for loading data into DeepTCR.

Release History

1.1

Initial release including two methods for unsupervised learning (VAE & GAN). Also included ability to handle paired alpha/beta data.

1.2

Second release included major refactoring in code to streamline and share methods across classes. Included ability for algorithm to accept v/d/j gene usage. Added more analytical fetures and visualization methods. Removed GAN from unsupervised learning techniques.

1.2.7

On-graph clustering method introduced for repertoire classifier to improve classification performance.

1.2.13

Ability for HLA information to be incorporated in the analysis of TCR-Seq.

1.2.24

Added ability to do regression for sequence-based model.

1.3

Third release including improved repertoire classification architecture. Details in method will follow in manuscript.
