Make a OrganismDb object from annotations available at the UCSC Genome Browser

Description

The makeOrganismDbFromUCSC function allows the user to make a OrganismDb object from transcript annotations available at the UCSC Genome Browser.

Usage

makeOrganismDbFromUCSC(
        genome="hg19",
        tablename="knownGene",
        transcript_ids=NULL,
        circ_seqs=NULL,
        url="http://genome.ucsc.edu/cgi-bin/",
        goldenPath.url=getOption("UCSC.goldenPath.url"),
        miRBaseBuild=NA)

Arguments

genome	genome abbreviation used by UCSC and obtained by ucscGenomes()[ , "db"]. For example: "hg19".
tablename	name of the UCSC table containing the transcript annotations to retrieve. Use the supportedUCSCtables utility function to get the list of supported tables. Note that not all tables are available for all genomes.
transcript_ids	optionally, only retrieve transcript annotation data for the specified set of transcript ids. If this is used, then the meta information displayed for the resulting OrganismDb object will say 'Full dataset: no'. Otherwise it will say 'Full dataset: yes'.
circ_seqs	a character vector to list out which chromosomes should be marked as circular.
url	Deprecated (will be ignored).
goldenPath.url	use to specify the location of an alternate UCSC Genome Browser.
miRBaseBuild	This argument is defunct.

Details

makeOrganismDbFromUCSC is a convenience function that feeds data from the UCSC source to the lower level OrganismDb function. See ?makeOrganismDbFromBiomart for a similar function that feeds data from a BioMart database.

Value

A OrganismDb object.
