This directory contains alignments of the following assemblies: - target/reference: Chicken (galGal2, Feb. 2004, Chicken Genome Sequencing Consortium Feb. 2004 release) - query: Mouse (mm8, Feb 2006, NCBI Build 36) Files included in this directory: - md5sum.txt: md5sum checksums for the files in this directory - galGal2.mm8.all.chain.gz: chained blastz alignments. The chain format is described in http://genome.ucsc.edu/goldenPath/help/chain.html . - galGal2.mm8.net.gz: "net" file that describes rearrangements between the species and the best Mouse match to any part of the Chicken genome. The net format is described in http://genome.ucsc.edu/goldenPath/help/net.html . - axtNet/*.galGal2.mm8.net.axt.gz: chained and netted alignments, i.e. the best chains in the Chicken genome, with gaps in the best chains filled in by next-best chains where possible. The axt format is described in http://genome.ucsc.edu/goldenPath/help/axt.html . The chainSwap program was used to translate mm8-referenced chained blastz alignments to galGal2 into galGal2-referenced chains aligned to mm8. See the download directory goldenPath/mm8/vsGalGal2/README.txt for more information about the mm8-referenced blastz and chaining process. Chained alignments were processed into nets by the chainNet, netSyntenic, and netClass programs. Best-chain alignments in axt format were extracted by the netToAxt program. All programs run after blastz were written by Jim Kent at UCSC. ---------------------------------------------------------------- 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/galGal2/vsMm8/. To download multiple files, use the "mget" command: mget ... - or - mget -a (to download all files in the current directory) All files in this directory are freely available for public use. -------------------------------------------------------------------- References Harris, R.S.
