Custom browser with ensembl genomes

[RichardJActon]

I've been testing out JBrowseR, (thanks for developing it, it looks great for several use-cases I have), and I've been having trouble setting up a custom browser.

I copied your example from the custom browser tutorial and swapped out the example genome for the build I'm interested in using:

ftp://ftp.ensembl.org/pub/release-91/fasta/caenorhabditis_elegans/dna_index/Caenorhabditis_elegans.WBcel235.dna.toplevel.fa.gz

This did not work, the assembly shows up in the drop-down but there is an indefinite loading circle with the open and show all regions in assembly buttons greyed out.

I'm note sure if it would be expected to work over ftp as I can't remember if this supports Byte serving as you mentioned in the creating URLs guide:

https://gmod.github.io/JBrowseR/articles/creating-urls.html

So I tried downloading the ensmbl data to a local directory and serving it with serve_data but got the same result

Any idea what I'm missing?

Just tried running the example on my local machine with Rstudio desktop and it worked with serve_data. So I think the issue with serve_data was arising from something to do with the network setup to I have access the remote RStudio server instance running on my workstation. I think maybe the local server created is not accessible to the other one the shiny app is running in for some reason
