Hi! I have some data from Agilent G4112F whole human genome arrays. I would like to do some analysis of GO terms etc. and was wondering if the hgug4112a.db package still applies to the 'F' version. Looking at a few examples seems to suggeest that it does but it would be great if someone could confirm (or refute) this. cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan 85350 Freising, Germany http://mips.gsf.de/staff/pagel

Hi Philipp, yes, hgug4112a.db does apply to to 4x44k arrays (the F version). The differences between the 1x44k and the 4x44k arrays lie in the array geometry, the control probes (the 4x44k has some extra ones), and the position of probes*. The actual non-control probes have the same sequences, so they map to the same genes. This means that the annotation package applies as well. Francois *: a few probes are also present a few places in the arrays, and I think their number differs also.
