Would it be possible to add version 10 of the zebrafish genome to BS genome.

Thank you so much

Maybe the data in AnnotationHub are sufficient?

> library(AnnotationHub)
> hub = AnnotationHub()
snapshotDate(): 2015-07-17
> query(hub, "GRCz10")
AnnotationHub with 8 records
# snapshotDate(): 2015-07-17 
# $dataprovider: Ensembl
# $species: Danio rerio
# $rdataclass: FaFile, GRanges
# additional mcols(): taxonomyid, genome, description, tags, sourceurl,
#   sourcetype 
# retrieve records with, e.g., 'object[["AH47053"]]'

Thank you, Martin.

After I posted here, I found the document on how to forge a BSgenome data package. I was able to generate the package following Herve Pages directions.
