What is the format for the gene identification data for cDNA arrays?
Various identifiers can be associated with each spot, such as spot numbers, well numbers, clone names, clone identifiers, probe set identifiers, UniGene identifiers, GenBank accession numbers, etc. The gene identifiers may be located alongside the expression data in the same files, or may be contained in a separate file which is used as a look-up table for the genes on all the arrays. If the gene identifiers are contained in a separate file, then there must be corresponding columns within the expression data file(s) and the gene identifier file, containing gene ids which can be used for matching the gene identifiers with the expression data. The column which is designated within BRB-ArrayTools as clone id should contain an organization-prefixed clone id (e.g., a prefix such as “IMAGE:”, “ATCC:”, “TIGR:” etc.). These clone ids can be used to link to clone reports in the NCBI database. Note that clone reports in the NCI mAdb database are only available for clones in the NCI Advanced Tech
