CrisprDNT

Transformer-based Anti-noise Model for Predicting CRISPR-Cas9 Off-Target Activities. image

PREREQUISITE

CrisprDNT was conducted by TensorFlow version 2.3.2 and python version 3.6.

Following Python packages should be installed:

  • numpy
  • pandas
  • scikit-learn
  • TensorFlow
  • Keras

Usage

For a new dataset：

  • You can process the dataset by calling code/data_process/create_coding_scheme.py to get the coding format needed by CrisprDNT.
  • Once you have the coding format for the new dataset, you can train and test the dataset using code/train&test/experiment.py, which contains the training procedure for CrisprDNT. The model architecture for CrisprDNT is described in detail in code/model/model_network.py, which also contains other models for off-target prediction.
