Calling all OrthoFinder users!

We’ve just released GLADE, a tool to infer gene gains, losses, duplications, and ancestral genomes across a phylogeny.

GLADE runs directly on OrthoFinder results.

Ok, I was slightly off: It was $45 (US) for 15 million paired end reads per sample, including lib prep, but excluding DNA extraction and labor, 192 samples pooled onto a NovaSeqX 3000M kit.

Anyway, at the same price and less work we get a nice metagenome of sufficient depth to get good community profiles as well as analysis of functional genes. No MAGs of course, but that is often not the objective.

This leads to higher costs, about 70 CAD per sample for amplicon sequencing perhaps including PCR and DNA extraction, but excluding the labor of manually extracting DNA and doing PCR, checking products with gels etc. That's the advantage of a large research conglomerate like Vienna I guess

marcstrous.bsky.social
🇨🇦 Marc Strous @marcstrous.bsky.social · Dec 1
Well that is really good value for your money! Here, we have problems making effective use of the higher sequencing capacity of the NextSeq instruments for amplicon sequencing as well as lacking effective robotics I guess. We have too few samples generated per month to reduce costs.
