    brest gay Using gff format in IGV.

    1. Do not omit the first line, especially for GFF 3.
    As IGV supports both of GFF ver 2 and GFF ver 3, the file needs to be distinguished.
    Do not miss the first line

    ##gff-version    3
    

    2. Make sure tab is used to separate fields.
    Even for the first line, there must be a tab between gff-version and 3.
    No space.

    Here are the specifications.
