This directory contains alignments of the following assemblies: - target/reference: Southern sea otter (enhLutNer1, Jun. 2019 (ASM641071v1/enhLutNer1), UCLA) - query: Human (hg38, Dec. 2013 (GRCh38/hg38), GRCh38 Genome Reference Consortium Human Reference 38 (GCA_000001405.15)) Files included in this directory: - md5sum.txt: md5sum checksums for the files in this directory - enhLutNer1.hg38.all.chain.gz: chained lastz alignments. The chain format is described in http://genome.ucsc.edu/goldenPath/help/chain.html . - enhLutNer1.hg38.net.gz: "net" file that describes rearrangements between the species and the best Human match to any part of the Southern sea otter genome. The net format is described in http://genome.ucsc.edu/goldenPath/help/net.html . - enhLutNer1.hg38.net.axt.gz: chained and netted alignments, i.e. the best chains in the Southern sea otter 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 . - enhLutNer1.hg38.synNet.maf.gz - filtered net file for syntenic alignments only, in MAF format, see also, description of MAF format: http://genome.ucsc.edu/FAQ/FAQformat.html#format5 - enhLutNer1.hg38.syn.net.gz - filtered net file for syntenic alignments only - reciprocalBest/ directory, contains reciprocal-best netted chains for enhLutNer1-hg38 The chainSwap program was used to translate hg38-referenced chained lastz alignments to enhLutNer1 into enhLutNer1-referenced chains aligned to hg38. See the download directory goldenPath/hg38/vsEnhLutNer1/README.txt for more information about the hg38-referenced lastz 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 lastz 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.soe.ucsc.edu, then go to the directory goldenPath/enhLutNer1/vsHg38/. 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.
