I have the impression that I'm the only one who wanted to load multiple data tracks in igv with one bedgraph.

I discovered it wasn't possible.

It seems easy to me to use each column of the bedgraph to make an igv track but as usual in this kind of case I must miss something.

I used to be a proto-mover.
Then, I read and wrote text files.

Wondering what's next.

Variant normalisation are left align, HGVS Nomenclature are 3' align.

CRY IN BIOINFORMATICS !

Playing with #vizitig again to prepare for the 1.0 release. This is the SNAP25 human gene expressed in 3 SRA datasets linked to cancers.
Exons have one color each, and exon junctions are in yellow.
The rest is new/noise.

A new release of niffler thank to
@luizirber.bsky.social
to say we must create a crate from my piece of code 6 year ago !

#rustlang
New release! niffler 3.0.0 is out!
crates.io/crates/niffl...

niffler is an utility crate to make it easy to work with compressed data.

For this release we worked on simplifying how features are activated for specific formats, giving more control to users (and less maintenance burden for us =])

Sometimes I spent 1 hour on my sunday evening to made clever change (const generic rust magic) and when I proof read my own PR, my reaction is:

It's clever, it's pretty, but it doesn't improve perf and it can create many problems. In fact, if I reviewed this PR, I'd probably reject it..

I think I can say if you want identify which genomic annotation overlap a variant superinterval are fast I didn't realy understand how but it's fast #rustlang #bioinformatics

It seems that one of my colleague's excel is still having a problem with the dates. This is the first time I've seen a genotype to date conversion.
