Columns in the results file are as follows:

rowid - just a row number
gene - official gene symbol
affyprobe - Affymetrix probe id
illuprobe - Illumina probe id
correl - Cross-platform rank correlation for the two probes.
explev.affy - Affymetrix expression level (log2 RMA)
explev.illu - Illumina expression level (raw)
affy.dist - Affymetrix distance from 3' end of the gene in bases.
illu.dist - Illumina distance from 3' end of the gene in bases.
affy.targ.start - Start base of the Affymetrix alignment to the genome (note that all locations are on the same chromosome)
affy.targ.end - End base of the Affymetrix alignment to the genome
illu.targ.start - Start base of the Illumina alignment to the genome
illu.targ.end - End base of the Illumina alignment to the genome
diff - The difference between the midpoints of the Affymetrix and Illumina targets.
affy.corr - Correlation of Affymetrix probe with the dilution profile
illu.corr - Correlation of Illumina probe with the dilution profile
max.corr.single - max(abs(affy.corr.ev),abs(illu.corr.ev))
