Javascript bio-sequence highlighter

Introduction

This is a lightweight javascript solution to highlight parts of the bio-sequence (DNA or protein, often in FASTA format), based on intervals (in BED format). See a working demo here.

Usage

The data/ folder contains a working example from converting Genbank file (.gb) to the required .fasta and .bed files. The demo page above loads the two required files and does the highlight accordingly - based on the styles pre-defined in a .css file.

Known issues

  • many feature types are nested, but often start at the same location. For example, the exon is a child of gene. Currently the hierarchy of features are not modeled, resulting in errors depending on which tag gets inserted first.
