I realize Rhesus macaques - Macaca mulatta are already on BSGenomes - but the long-tailed macaque genome is also available and they are also widely used as major biomedical model. As such, I wanted to see if it might be a candidate for being added to the BSGenome list.
The genome can be found here:
http://www.ncbi.nlm.nih.gov/genome/776
My lab is also working with several parasites of macaques including Blastocystis spp and Plasmodium spp that coinfect humans - I'm going to be compiling my own BSGenome packages for those, but common parasites like those are good options for more permanent additions to BSGenomes I'd be happy to provide links.
Cheers,
Amy
