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.
pip install st_forna_component
Look at the example for a simple example:
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 '&'
