biomaRt Ensembl version 83 (mouse)

Question

[Marie-Michelle]

Hello,

I'm looking for an old Ensemb release (83) for GRCm38 build:

library(biomaRt)
mouse <- useEnsembl(biomart = "genes", dataset="mmusculus_gene_ensembl", version=83)

Error: Specified Ensembl version is not available.
Use listEnsemblArchives() to view available versions.

Version 83 is not displayed in the list of Ensembl archives ; is there another way to have access to this version?

Thank you!

I don't think so, at least not through BioMart. Check this table to see which version of ensembl that is the closest that has the assembly you are looking for and use that: https://www.ensembl.org/info/website/archives/assembly.html

Depends what you need. You can browse the archive directly at https://ftp.ensembl.org/pub/release-83/ so maybe what you need can be found there.
