Hi all, There was a problem with the mailing list that prevented some posts from last week from getting through. We believe the problem has been resolved and that any held messages have been resent (but some dups had to be resent, sorry). If you do not see your post on the list within 12hrs, I'd like to know about it. + seth -- Seth Falcon | Computational Biology | Fred Hutchinson Cancer Research Center BioC: http://bioconductor.org/ Blog: http://userprimary.net/user/
