Why do same GSE IDs like GSE18 have different GEO DataSet (GDS) ID numbers. On what basis you differentiate GDS, GSE and GSM Ids
Some submissions have undergone a curation process at GEO, giving them a GDS accession. NCBI has not been curating data for several years, so the GDS accessions are historical and now represent a pretty small proportion of the GEO information. A GDS and GSE represent pretty much the same type of data, a collection of samples. A GSM is a single sample in GEO. Therefore, GDS and GSE contain one or more GSMs.
Hi. Sean Davis,
I have already gone though the GEO database, but it doesn't answer my question. In GEOmetadb, I found some unique GDS IDs like GDS15, GDS16, GDS17, GDS18, GDS19, GDS20, GDS21, GDS30 and GDS31 with common GSE ID - GSE18. My question is on what basis are these GDS IDs are common to GSE18. Also, they belong to different GPL IDs like GPL51, GPL52 and GPL53.
