Map between Manufacturer Identifiers and cytogenetic maps/bands

Description

rae230aMAP is an R object that provides mappings between manufacturer identifiers and cytoband locations.

Details

Each manufacturer identifier is mapped to a vector of cytoband locations. The vector length may be one or longer, if there are multiple reported chromosomal locations for a given gene. An NA is reported for any manufacturer identifiers that cannot be mapped to a cytoband at this time.

Mappings were based on data provided by: Entrez Gene ftp://ftp.ncbi.nlm.nih.gov/gene/DATA With a date stamp from the source of: 2011-Sep14

Examples

        x <- rae230aMAP
        # Get the probe identifiers that are mapped to any cytoband
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the MAP for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
