[BioC] How to use cutome reference genome?

[Yan He [guest]]

Hi,
I am trying to use the MEDIPS package in Bioconductor. The tutorial says that one of the supplied reference genomes must be used. Does anyone know how to produce a custom reference genome in case one's genome of interest is not one that list? I am directed to BSgenome by the same question posted by Kelly V.. However, the BSgenome is based on the Biostrings-based genome data package. What should I do if I have my own sequenced genome sequence and not published yet?

Thanks very much for your help!

Yan
