SigmaP: Python package for predicting sigma70 promoter in Escherichia coli K-12

Project description

SigmaP

Python package for Sigma70 promoter Prediction. This package used Sigma70Pred (Patiyal et al. 2022).

Installation

This package can be installed by pip.

pip install sigmap

How to use

First, prepare fasta file containing DNA sequence. Minimum length for prediction is 81nt. Then, calculate probability score by SigmaFactor. Run prediction model by .predict method. Results will be returned as pd.DataFrame.

from sigmap import SigmaFactor

sigma = SigmaFactor()

df_out = sigma.predict('tutorial/example_seq.fa')
