A python library to explains molecular patterns (SMARTS)
Project description
👀 smarts-explainer
SMARTS explainer is a small wrapper around the [SMARTSview](https://smarts.plus/)
tool developped at ZBH U. Hamburg for creating an easy to comprehend visualization for SMARTS expression. The concept was developed K. Schomburg and M. Rarey.
Installation
smarts-explainer
requires datamol
and requests-toolbelt
. You can install it as follows
pip install smarts-explainer
Alternatively, download, install the dependency then install it with:
git clone git@github.com:maclandrol/smexplainer.git
cd smexplainer
mamba env create -f env.yml -n "smexplainer" && conda activate smexplainer
pip install -e .
Usage
import smexplainer
my_smarts = "c12c(n(C)c(=O)[nH,$(nC)]c(=O)1)ncn2C"
smexplainer.explain(my_smarts, filetype="png")
For a batch of smarts, you can use the smexplainer.batch_explain
function instead
