Presence-Absence Calls from Negative Strand Matching Probesets
Description
A function to make gene presence/absence calls based
on distance from negative strand matching probesets (NSMP)
which are derived from Affymetrix annotation. PANP is applied
after gene expression values are created, and therefore can be
used after any preprocessing method such as MAS5 or GCRMA, or
PM-only methods like RMA. NSMP sets have been established for
the HGU133A and HGU133-Plus-2.0 chipsets to date.
