Create MetaProbeset File for APT function “apt-probeset-summarize”.

1	metaProbesets(xps.scheme, infile = character(0), outfile = character(0), exonlevel="metacore")

`xps.scheme`	exon `SchemeTreeSet`.
`infile`	Name of file containing exon transcript\_cluster\_ids.
`outfile`	Name of resulting file containing meta probeset definitions.
`exonlevel`	exon annotation level determining which probes should be used.

This function allows to create a metaprobeset file for APT function “apt-probeset-summarize” to be used with option “-m”. The infile must contain exon transcript\_cluster\_ids, one per line, e.g. one can export the rownames(data.rma)
The resulting file may be useful if you want to compare results created with xps to results created with APT function “apt-probeset-summarize”.
