qc.probes {simpleaffy} | R Documentation |
Contains the names of QC probes used on different chips
A CSV file, with a column for each spike.
Affymetrix arrays contain a set of QC probes designed to check for full length transcripts. Most arrays contain probes targeted at the 3' 5' and mid regions of the GAPDH and beta-actin transcripts. If all is well, the ratios between signal at either end of the transcripts should not be 'too large'.
This object contains a table of the probeset ids used on each array.
