make IGV not to show chromosomes

Question

[Lalit]

I used genometools to sort a gff3 file, there are chromosomes coordinates in the sorted file. When I visualize this file in IGV, it shows the chromosome as a sequence as well. This makes it hard to distinguish between genes and other features. Is there a way to not show chromosomes in IGV? or the GFF file can be edited.

PS: I do not want to go and remove individual chromosome features from gff file.

I do not want to see the topmost blue line(chromosome) in the screenshot:

Post a screenshot of what you are looking for (highlight parts you don't want to see).

If the chromosome is a feature in the GFF file, then it might be the easiest to remove them from the file?

Maybe something like grep -v "chromosome:" original.gff > modified.gff already does the job, but it may also be slightly more complicated depending on the naming scheme etc.

Thanks removing chromosome from sorted gff file with the above command worked.
