Forna Component

RNA Secondary Structure Visualization Using a Force Directed Graph Layout

This is a simple component that renders a forna diagram. It is a wrapper around the forna container.

Installation

pip install st_forna_component

Example

Look at the example for a simple example:

Usage

import streamlit as st
from st_forna_component import forna_component

return_value = forna_component(
                                structure = '((((....))))', # RNA structure
                                sequence =  'AAAAUUCGUUUU', # RNA sequence
                                height = 400, # height of the component
                                animation = animation, # boolean to enable animation/interactivity
                                zoomable = zoomable, # boolean to enable zooming
                                label_interval = label_interval, # interval for numbering the nucleotides
                                node_label = node_label, # boolean to enable node labeling
                                editable = editable, # boolean to enable editing
                                color_scheme = color_scheme, # color scheme for the nucleotides: options are 'structure', 'sequence', 'positions', 'custom'
                                colors = colors, # custom colors for the nucleotides: string with space separated index:color pairs
                                )

 
st.write("Received value:", return_value) 
# Returns None if no changes were made. 
# When clicked on the component, it returns the current structure and sequence 
# In case of cofold, it return a unique string without the separator '&'
