Dear sir:
I downloaded the blastz result of mm9 vs hg18 from
http://hgdownload.cse.ucsc.edu/goldenPath/mm9/vsHg18/axtNet/ . But I
found the location numbers of hg seqs in those files are strange.
For example:

3 chr21 9885041 9885155 chr12 5667727 5667849 - 771
GGTCAAGTAACTGAGGACAAGGATCAATAGAAACAAGGACACACTCTAATTTTATGATAAATATTTTATTCAAGAGTCACCGTATACAGAAAATTCAAAG---------------ATTAGTAAAGGCCCt
GATTAAATCATTAAGGA-AGGGAATAAAAACACTATGAACTCATTC---TCTTTTAATTGGTAATTTTCCCAA---TCGCTCTTCATGCAAGATGTAGAGTGAAGGGCCCTCTCAGTTAGTAAAGCTTTT

As described, the human seq block is located at "chr12 5667727
5667849"; But in fact, the latter sequence is at
"chr1:42836935-42836958". You can confirm that with Blat tools.

Thank you! I appreciate your time very much!
