Hi Alexandre, The "Affy U133Plus2" track maps probe locations for affymetryx U133 plus 2.0 and is available for hg18 (Mar. 2006) in the Expression track group. The BLAT parameters used to map this track are located on the track description page (click on "Genome" in the top blue bar, select hg18, click submit, click on track name in Expression track group). To download the entire psl file, go to our home page, click on "Downloads" (approximately half-way down the blue side bar). From the downloads page click on "Human", scroll down to the hg18 assembly and click on "Annotation Database". This will take you to a directory that contains all the database tables for hg18, including affyU133Plus2.txt.gz, which should be the file you are looking for.
You can also use the Table browser (http://genome.ucsc.edu/cgi-bin/hgTables) to download portions of the the file. I hope this information is helpful. Please feel free to contact the mail list again if you require further assistance.
