Get mappings between GPL and Bioconductor microarry annotation packages

Share:

Description

Query the gpl table and get GPL information of a given list of Bioconductor microarry annotation packages. Note currently the GEOmetadb does not contains all the mappings, but we are trying to construct a relative complete list.

Usage

1
getBiocPlatformMap(con, bioc='all')

Arguments

con

Connection to the GEOmetadb.sqlite database

bioc

Character vector of Biocondoctor microarry annotation packages, e.g. c('hgu133plus2','hgu95av2'). 'all' returns all mappings.

Value

A six-column data.frame including GPL title, GPL accession, bioc_package, manufacturer, organism, data_row_count.
