Mapping Microarray Chip Feature Ids to Gene Ids for Microarray Platforms in Ncbi Geo
نویسندگان
چکیده
The Gene Expression Omnibus or NCBI GEO (http://www.ncbi.nlm.nih.gov/projects/geo/) is one of the most comprehensive public repositories of microarray data. The data in NCBI GEO is organized into samples, series, datasets and platforms. Platform files specify the characteristics of a particular type of microarray chip, including a mapping of chip features to genetic features. These mappings are not standardized. This technical note describes a program GPLGeneMap that reads a platform specification in XML format and produces a mapping of chip features to NCBI Gene IDs. The mapping strategy is based on a user specification given in an XML file. The program produces a mapping file and a list of chip features that it was unable to map.
