The makeTranscriptDbFromUCSC() function is defined in the GenomicFeatures package. I just added the 'url' and 'goldenPath_url' arguments to it, so, *in theory*, the user now should be able to specify the location of an alternate browser. The default values for these arguments are: url="http://genome.ucsc.edu/cgi-bin/" goldenPath_url="http://hgdownload.cse.ucsc.edu/goldenPath" so, by default, makeTranscriptDbFromUCSC() is using the browser at Santa Clara. To use another browser (e.g. one of the mirror listed on http://genome.ucsc.edu/mirror.html), one would need to do something like: > makeTranscriptDbFromUCSC(genome="sacCer2", tablename="ensGene", url="http://genome.hmgc.mcw.edu/cgi-bin/") Error in .local(.Object, ...) : Failed to obtain 'hguid' cookie The problem is that I get this error with all the browser mirrors I tried. I don't know if it's an issue with the configuration of the remote browser, or with the rtracklayer::browserSession() function that is used behind the scene by makeTranscriptDbFromUCSC() to connect to the remote Genome Browser: > library(rtracklayer) > session <- browserSession(url="http://genome.hmgc.mcw.edu/cgi- bin/") Error in .local(.Object, ...) : Failed to obtain 'hguid' cookie I'm cc'ing Michael Lawrence, the author and maintainer of rtracklayer.
