\begin{Description}\relax
ath1121501CHRLOC is an R object that maps manufacturer identifiers to the
starting position of the gene. The position of a gene is
measured as the number of base pairs.
\end{Description}
\begin{Details}\relax
Each manufacturer identifier maps to a named vector of chromosomal locations,
where the name indicates the chromosome. Due to inconsistencies that
may exist at the time the object was built, these vectors may
contain more than one chromosome and/or location. If the chromosomal
location is unknown, the vector will contain an \code{NA}.

Chromosomal locations on both the sense and antisense strands are
measured as the number of base pairs from the p (5' end of the sense
strand) to q (3' end of the sense strand) arms. Chromosomal locations on the
antisense strand have a leading "-" sign (e. g. -1234567). 

Mappings were based on data provided by: Tair ( ftp://ftp.arabidopsis.org/Maps/seqviewer\_data/sv\_gene.data ) on 2007-Aug2

\begin{Examples}
\begin{ExampleCode}
        x <- ath1121501CHRLOC
        # Get the probe identifiers that are mapped to chromosome locations
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the CHRLOC for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
