Retrieve information about GEO series (GSE) records present in the compendium database
character vector specifying the GSE ID(s). The default value
An object of class
data.frame consisting of ten columns: i) ID of
the record in the compendium database, ii) GSE ID, iii) educated
guess on the experimental design of the experiment, iv) GPL ID, v) number of
samples, vi) user-specified tag for the experiment, (see
tagExperiment), vii) NCBI taxonomy ID, viii) corresponding
organism name, ix) GDS ID and x) date and time on which the data
was loaded in the database
The value for the variable
experimentDesign is determined by
parsing the sample information provided by GEO. The variable can take
the following values:
i) SC: single-channel design, ii) DC: double-channel design, iii) DS:
double-channel dye-swap design (if the same source name occurs in both
channels) and iv) CR: double-channel common reference design (if the
source name is equal for all samples in one of the two channels). The
attribution of 'DS' and 'CR' labels makes assumptions on how source
names are represented in GEO and should be interpreted with caution.
