Extra feature annotation for the GEO dataset GSE3649.
We extracted and save in a file the GenBank accession
numbers from the feature annotation data of the original
ExpressionSet object -- created with
getGEO, which does not contain
many annotation.
The content of the file (a list of GenBank IDs, one per
line) was passed to IDconverter (see Reference) to obtain
further annotation (ENTREZID, UNIGENE, ...). We used this
online service because no annotation were available for
these accession numbers in the organism annotation
package org.Hs.eb.
