Probably a basic question but it's difficult to find information on the subject...

When viewing a GTF and BED file in IGV, there seems to be differences in colour (BED track can't be recoloured, just shows as black, GTF can be recoloured). Does anyone know the reason for this? I thought that the GTF and BED formats contained predominantly the same information just in different formats.

Thanks!
<p>BED was originally designed to contain color specification for each row in column 9. In addition it can contain a number of track definitions in the header that can further specify the colors. Using these have fallen out of favor (thankfully so I might add) but IGV seems to stick with the more strict definition of reading the color from the rows themselves.</p>
