Build BSgenome packages for
any species, any assembly,
automatically.
Paste an NCBI accession, an Ensembl species URL, or upload your own FASTA. We build the BSgenome package and hand you an installable tarball. No R, no Bioconductor, no local toolchain to set up.
Quick start
Pick one of two paths.
Path A
Search an existing package.
Browse a growing community repository. Filter by species, assembly, provider, or accession; install the result with a single R command.
Open package browserPath B
Build your own package.
Paste an NCBI accession or an Ensembl species URL. We fetch metadata, generate a clean BSgenome source package, and hand you an installable tarball.

Every BSgenome on Bioconductor took an expert and an afternoon to assemble. AutoBSgenome turns that into a paste-and-wait web service. Anyone, any genome, install-ready in minutes.
