Millions of Single-Cell Analyses Yield Most Comprehensive Human Cell Atlas Yet

There are 37 trillion or so cells in our bodies that work together to give us life. But it may surprise you that we still haven’t put a good number on how many distinct cell types there are within those trillions of cells.

New in RAPT: Better taxonomic assignment and GO annotation

We are excited to announce two improvements to the Read assembly and Annotation Pipeline Tool (RAPT), which allows you to assemble genomic reads for bacterial or archaeal isolates and annotate their genes at the click of a button. Improved taxonomic assignment Now RAPT verifies the scientific name you provide with the reads, and corrects it … Continue reading New in RAPT: Better taxonomic assignment and GO annotation

Announcing Human Annotation Release 110

The annotation of human assemblies GRCh38.p14 and T2T-CHM13v2.0 We are happy to announce the first de novo annotation of human T2T-CHM13v2.0, the gap-less assembly generated by the T2T Consortium, and the full re-annotation of the human reference assembly, GRCh38.p14. We hope the results will serve both the needs of those eager to explore newly sequenced regions of the genome, including … Continue reading Announcing Human Annotation Release 110
