Pairwise platform gene classification based on susceptibility to alternative splicing

Platform A	Platform B	Common Genes	Equal A = B	Disjoint A ⋂ B = Ø	A\B ≠ Ø	B\A ≠ Ø
Affymetrix	Agilent	5804	1964	158	1599	3461
Affymetrix	Codelink	6429	2808	85	2526	2623
Agilent	Codelink	5183	1648	196	1450	3173

Let A be the set of transcripts a probe(set) on platform A targets

Let B be the set of transcripts a probe(set) on platform B targets

Equal A = B : Number of genes in which platform A and B target equal transcript sets.

Disjoint A ⋂ B = Ø: Number of genes in which platform A and B target disjoint transcript sets.

A\B ≠ Ø: Platform A and B target the same gene, but platform A targets extra transcripts that B does not.

B\A ≠ Ø: Platform A and B target the same gene, but platform B targets extra transcripts that A does not.

Note: The total number of classified genes can exceed the number of common genes because a gene may be a member of both A\B = Ø and B\A = Ø.
