Question

[greatgene719]

Hello,

How can I change the arrow size in the transcripts made by Gviz? I mean the line that connects the exons showed with several arrows to tell which strand a given transcript is located.

Thanks

Hi, you can change the arrow size using min.height display parameter in GeneRegionTrack.
