________________________________ From: Maratou, Klio Sent: Mon 12/02/2007 11:00 To: [EMAIL PROTECTED] Subject: query output inconsistency I have a question about an inconsistency that I found when I query the biomart Rattus norvegicus genes (RGSC3.4) dataset. If under Filters I use the chromosome number along with base start and end positions to query biomart, then I get a specific number of genes that are in this genomic interval. However, if I repeat this query using marker names for start and end, then I get a different number of genes for the same genomic interval. The sequence start and end positions that I use are based on the sequence positions of the markers. Why is there a difference in the output?
