Is there any "standard" or "recommended" way to annotate the metadata of GenomicRanges objects with the reference genome, in particular GRangesList and RangedSummarizedExperiment? I looked to parathyroidSE for an answer, and the closest I found was:

> metadata(rowRanges(parathyroidGenesSE))$genomeInfo$`BioMart dataset version`
[1] "GRCh37.p11"

Unless I misunderstand, it's just:

genome(parathyroidGenesSE) <- "GRCh37"

Thanks Michael.  I can for the objects I care about, although not for parathyroideGenesSE:

> library(parathyroidSE)

> data(parathyroidGenesSE)

> genome(parathyroidGenesSE) <- "GRCh37"
Error in methods::slot(object, name) : 
  no slot of name "call" for this object of class "GRangesList"

> class(parathyroidGenesSE)
[1] "RangedSummarizedExperiment"
attr(,"package")
[1] "SummarizedExperiment"

> seqinfo(parathyroidGenesSE)
