RNADiscrepancy 0.1.0

Compute discrepancy between 3D RNA (sub)structures

RNADiscrepancy

Isostericity and Discrepancy

Geometric discrepancy is a similarity measure between RNA 3D structures Isodiscrepancy is a similarity measure between two pairs of interacting RNA nucleotides

This package aims to provide easy interfaces to compute these values and visualize their alignments.

Requirement

- numpy
- scipy

Usage exemple

Loading raw data

For each nucleotide we need

1. list of atom names
2. list of atom elements
3. list of atom positions
4. RNADiscrepancy.rawdata_format_nucleotide to format raw data
5. RNADiscrepancy.isodiscrepancy to compute isodiscrepancy
