TAT

Transcriptomics-to-Activity Transformer is a deep learning model to predict compound bioactivity in a dose-response assay using compound-induced transcriptomic profiles over concentration.

Contents

  • tat: Python source code for TAT.

System requirements

Hardware

GPUs

We have tested TAT on machines with the following GPUs:

  • NVIDIA Tesla V100
  • NVIDIA Ampere A100

Software

Operating systems

We have tested TAT on machines with the following systems:

  • Red Hat Enterprise Linux 8
  • CentOS Linux 7

Software dependencies

  • python 3.8.15
  • pandas 1.5.2
  • numpy 1.23.5
  • pytorch 1.12.1.post200
  • rdkit 2022.09.3
  • scikit-learn 1.2.0
  • matplotlib 3.6.2
  • seaborn 0.12.2
  • skorch 0.9.0

Installation

  • Install the python libraries mentioned in Software dependencies above into your python environment.

Example dataset

An example dataset with transcriptional signatures over concentration can be downloaded from https://broad.io/rosetta/. The example dataset is LINCS-Pilot1.

Training and validating a model

With the example LINCS dataset, we show how to build a TAT model that takes as input the transcriptional signatures over concentration of compounds to predict a compound-induced morphological feature in a Cell Painting assay.

Make sure to modify the data directory path in preprocess.py to ensure that the code finds the LINCS data.

cd ./tat
python preprocess.py
python model_build.py
