Hi Patrik,
You cannot re-load a genome that is already in your IGV pulldown menu,
but you can work around it like this:
1. Switch to a different genome (ie not hg19) in the genome pulldown menu.
- If there's only hg19 in your pulldown menu, you'll need to load
another genome from the server - it doesn't matter which one.
2. Go to Genomes > Manage Genomes and remove the hg19 genome.
3. Go to Genomes > Load from Server and select the hg19 genome and check
the "Download sequence" box.
Note that this limitation has been removed in IGV
2.4 beta.
