Absolutely. In the amplicon/microbiome sequencing space the chimeras and homopolymer errors with illumina were more easily recognizable. Particularly paired end chemistries, since you can throw away all the <100% completely overlapping reads.

FWIW, Roche 454 sequencing ruined our final microbial ecology undergrad capstone project in undergrad.

I think there's a generation of scientists that never really had to deal with homopolymer errors, since illumina short reads were the norm for a long time. While, now, in the long read era, we're back to homopolymer errors.

Interesting thread y'all. Hi-C makes sense with Euks where the structure is a lot more physically defined, seems like early days for protocols for anything not euk-structural variant related.

Spatial structure: shaping the ecology and evolution of microbial communities Spatial structure naturally emerges in microbial communities, shaping growth, interactions, and evolution, and revealing how microscale processes scale up

Most microbes don't live in shaking flasks; spatial structure shapes how microbes interact and evolve at every scale, as we discuss in our recent review @jeroenmeijer.bsky.social @simonvanvliet.bsky.social @bedutilh.bsky.social @bramvandijk.bsky.social and others

I think the tech changing quickly is why I'm very pro-single purpose software so it's easily swapped out.
