Create an exon intron map for alternative spliceforms with decorations

Getting Started in the browser

• exons are in UPPERCASE and introns in lowercase
• sequences supplied in fastA format with line break \n after identifier

let myMap = new exonIntronMap(">C10G8.5a\nATGACTCGATTAGGGTGTTGGCTAGCAGTAGCCTTTCTGGTGGCCCTCGCTGGACTCGCAGATGCTGGATCCAACTGTTCAGCAGCCGACGCCACTAGAAACTGCATCGATGGACTTGTTATACCTATTTGgtgaggatttaaactaaaacaaagcttgaat>C10G8.5b\nATGACTCGATTAGGGTGTTGGCTAGCAGTAGCCTTTCTGGTGGCCCTCGCTGGACTCGCAGATGCTGGATCCAACTGTTCAGCAGCCGACGCCACTAGAAACTGCATCGATGGACTTGTTATACCTATTTGgtgaggatttaaactaaaacaaagcttgaatcaaaatttga>C10G8.5c\nATGAAGGAGGGAGAGATCGTTTTTGAAGACAACCAGACTGAgtacatcacctaccaatatcgtttttcttcaactttttttccagAGCTCTTGTTGAAATTGGAATTGTCGATACTGAACAATACGAACGCTCCGACTACTTCTACATCGAGCTTTCCCCACCAATCTGGGCCAAGAAGATGAATGgtgagtatttttggaactatttttttaagtgaaacaacaaaaacgcttctacatatacatatgtgcacattgttaatttcactacaacaacacaacaacaaaaacaatcaattaat");
		

• add coordinates to position the spliceforms relative to one another and correctly number the scale
• Must be supplied in the same order as the sequences

myMap.coords = "5303692,5303692,5307700";

• label the scale:

  myMap.chromosomeName = "Chromosome II";
  

• add decorations:
  1. SNP

     myMap.snpPoint = 3800;
     const Arrow = '\u2192';
     myMap.snpText = "ATG" + Arrow + "GTG";
     

  2. Deletion

     myMap.deletion = "1200,1650";
     myMap.delName = "ems deletion";
     

  3. Insertion

     myMap.knockinPoint = 5650;
     myMap.knockinText =  "GFP CRISPR insert";
     myMap.knockinColor = "green";
     

1. render the SVG image

   myMap.render();
   

From npm

• npm install biojs-vis-exon-intron-map

Output

• Exon intron graphic with lesion decorations in high resolution Scalable Vector Graphics (SVG) format

Example directory

• sample files are rendered from the examples dir at the BioJS registry
• note: it takes a minute to render the sample files at BioJS
