This directory contains alignments of the zebrafish assembly (danRer1, Nov. 2003) to the mouse assembly (mm5, May 2004) in "axt" format. For a description, see http://genome.ucsc.edu/goldenPath/help/axt.html. The alignments were produced by the blastz alignment program, which is available from Webb Miller's lab at Penn State University (http://www.bx.psu.edu/miller_lab/). The blastz scoring matrix used was: A C G T A 91 -90 -25 -100 C -90 100 -100 -25 G -25 -100 100 -90 T -100 -25 -90 91 with a gap open penalty of 400 and a gap extension penalty of 30. The minimum score for an alignment to be kept was 6000 for the first pass and 2000 for the second pass, which restricted the search space to the regions between two alignments found in the first pass. Each chromosome was divided into 10,000,000 base chunks for the blastz alignments and all repeats for each organism were used as lineage-specific repeats. Repeats were detected with Arian Smit's RepeatMasker program using a zebrafish repeats library. The .lav format blastz output, which does not include the sequence, was converted to .axt with lavToAxt. Low scores can occur using the scoring matrix above and with repeats abridged; therefore, alignments were rescored using PSU's restore_rpts program and the default scoring matrix: A C G T A 91 -114 -31 -123 C -114 100 -125 -31 G -31 -125 100 -114 T -123 -31 -114 91 -------------------------------------------------------------------- If you plan to download a large file or multiple files from this directory, we recommend you use ftp rather than downloading the files via our website. To do so, ftp to hgdownload.cse.ucsc.edu, then go to the directory goldenPath/mm5/vsDanRer1/. To download multiple files, use the "mget" command: mget <filename1> <filename2> ... - or - mget -a (to download all the files in the directory) All the files in this directory are freely usable for any purpose. All zebrafish sequence data are made available before scientific publication with the understanding that the groups involved in generating the data intend to publish the initial large-scale analyses of the dataset. This will include a summary detailing the data that have beeen generated and key features of the genome identified from genomic assembly and clone mapping/sequencing. Any redistribution of the data should carry this notice. -------------------------------------------------------------------- References Chiaromonte, F., Yap, V.B., and Miller, W.
