highlight specific exon with different color

[lldelisle]

Hi,
Indeed we only allow different colors for CDS (coding) and UTR (non-coding). If you want to highighlight some exons, you can modify your bed12 so that the exons you want to highlight are the CDS and all the rest are non coding.
In a bed12 the CDS id defined in columns 7 and 8 see UCSC FAQ.
So if you modify the columns 7 and 8 you can get the resired output:

• Set all columns 7 and 8 to the same value as column 2.
• Change columns 7 and 8 for the intervals with exons you want to highlight with the coordinates of the exon.
  For example:

cat original.bed12 | awk -v OFS="\t" '{if ($4=="the name of your gene"){$7=start of highlight exon;$8=end of highlight exon}else{$7=$2;$8=$2};print}' > modified.bed12
