I did some study and found that chromosomal location data are indexed from the p to q arm on the +strand but from q to p arm on the -strand, which agrees with what the biologists were telling you. I wrote to a person in UCSC Human Genome project about this but have not get any confirmation back yet.

JZ: Indexing to the ends of genes seems like an error --it makes for inconsistency in the interpretation of CHRLOC. I went ahead and downloaded UCSC tables and fixed the error in my local work. What I did was: download various UCSC tables, look for - strand genes, use the opposite (largest available) index (start of transcription index) as the CHRLOC for the - strand genes. Hope this helps.
