This directory contains alignments of the following assemblies: - target/reference: Human (hg38, Dec. 2013 (GRCh38/hg38), GRCh38 Genome Reference Consortium Human Reference 38 (GCA_000001405.15)) - query: American alligator (GCF_030867095.1_rAllMis1, 2023-08-24, Vertebrate Genomes Project) Files included in this directory: - md5sum.txt: md5sum checksums for the files in this directory - hg38.GCF_030867095.1.all.chain.gz: chained lastz alignments. The chain format is described in http://genome.ucsc.edu/goldenPath/help/chain.html . - hg38.GCF_030867095.1.net.gz: "net" file that describes rearrangements between the species and the best American alligator match to any part of the Human genome. The net format is described in http://genome.ucsc.edu/goldenPath/help/net.html . - hg38.GCF_030867095.1.net.axt.gz: chained and netted alignments, i.e. the best chains in the Human 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 . - hg38.GCF_030867095.1.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 - hg38.GCF_030867095.1.syn.net.gz - filtered net file for syntenic alignments only - reciprocalBest/ directory, contains reciprocal-best netted chains for hg38-GCF_030867095.1 The chainSwap program was used to translate GCF_030867095.1-referenced chained lastz alignments to hg38 into hg38-referenced chains aligned to GCF_030867095.1. See the download directory goldenPath/GCF_030867095.1/vsHg38/README.txt for more information about the GCF_030867095.1-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/hg38/vsGCF_030867095.1/. 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.
