[BioC] PM or MM spot intensities from CEL files

I would really appreciate if somebody could tell
whether it is possible to extract PM and MM spot (not
probe) intensities from CEL files. A CEL file has X
and Y coordinates and mean intensity associated with
each of these locations. I think each spot in an
Affymetrix array is either a perfect match or
mismatch. Although there is a method in the affy
package to extract PM and MM values for each probe I
found no method to find PM or MM spot intensity from
CEL files.

Thanking you in advance,
