Screen goes blank if you select a region starting at a node ID that does not have any threads associated with it

I think that's the explanation anyway. Literally everything disappears: the dropdown menus at the top, the actual visualization, the options menu at the bottom. Just a white Chrome window. It doesn't seem to crash the server though, because I can refresh the page and everything is still working fine.

Interesting, I've never seen this behavior and could not reproduce it. Does the node in question just have no haplotypes, or no reads as well?

Is this a small enough dataset that you could easily share it with me? Are there any console errors (visible via Chrome's developer tools)?

I agree that it's most likely a client issue, but theoretically it could be something on the server too. The server is set up to restart the application immediately if it crashes.

I think it also had no reads associated with it. Unfortunately I can't share the data though, we're under a bunch of data access restrictions with it.

I get completely blank screens when I try loading a file that's too big to handle for my local installation of IVG, could it be related to that? Reloading works fine in that case as well.

I think this may be related to my issue in #93

Would like to add I'm getting this same exact issue as well, and notably also with the provided example data (e.g. snp1kg-BRCA1). Sequencetubemaps and vg were both pulled and installed today with latest versions. It also happens when I load my own data.

[Nheyer]

do you have a position on snp1kg-BRCA1 where this occurs @briannadon

[briannadon]

No particular position @Nheyer. Just upon first loading up the map.
