Hi,
> The PLANdbAffy database provides flat files of probe annotation, assigned > by a reannotation pipeline that the authors designed. You can access it > here: http://affymetrix2.bioinf.fbb.msu.ru <http://affymetrix2.bioinf.fbb.msu.ru/>I've not looked at the flat file for U133 Plus 2 itself, but just entering the three probeset IDs you listed into their web form you can see the probes that make up the three probesets all map to different places. The three links below go to USCS with a track for each probeset shown. 206527_at - http://bit.ly/g8XcZK 209459_s_at - http://bit.ly/g5bPn8 209460_at - http://bit.ly/eU2mpG I imagine it would be fairly straightforward to download their flat file, break it up by probeset ID and then find the maximum and minimum coordinates of the constituent probes. -- Mike Smith PhD Student Computational Biology Group Cambridge University [[alternative HTML version deleted]] _______________________________________________ Bioc-sig-sequencing mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/bioc-sig-sequencing
