Support for nodes larger than 2^27 #143

Closed diego-rt closed 11 months ago

diego-rt commented 11 months ago

Hello,

I'm trying to visualise an assembly of a 30+ Gbp genome and some of the nodes are more than a few hundred megabases. I've realised that nodes larger than 134217728 bp are not processes by BandageNG and neither visualised or included in the statistics under graph information. Is there are chance assemblies with nodes of this size can be supported in the future?

Thanks!!

Are you sure you're using the latest version? We do support nodes up to ~1 Gbp (30 bits).

As far as I can tell, I am using v2022.09. Or should I try the continuous build?

asl commented 11 months ago

This is very old version. We are using rolling releases since then. The particular change was implemented ~year ago

Oh I see! Ok, I will give it a try. And what if my contigs ever surpass the 1 Gb mark? Our chromosomes are 1.5-4 Gb and we are aiming for T2T. I guess that would be difficult to implement?

Apologies, you are totally right. It works with the continuous build for macOS.

This is not something we're going to handle as it would increase memory consumption for all users drastically.
