This directory contains the Nov. 2020 (mRatBN7.2/rn7) assembly of the rat genome (rn7, Wellcome Sanger Institute), as well as repeat annotations and GenBank sequences. For more information about this assembly, please note the NCBI resources: https://www.ncbi.nlm.nih.gov/genome/73 https://www.ncbi.nlm.nih.gov/genome/assembly/9079111 https://www.ncbi.nlm.nih.gov/bioproject/662791 https://www.ncbi.nlm.nih.gov/biosample/SAMN16261960 Files included in this directory: rn7.2bit - contains the complete rat/rn7 genome sequence in the 2bit file format. Repeats from RepeatMasker and Tandem Repeats Finder (with period of 12 or less) are shown in lower case; non-repeating sequence is shown in upper case. The utility program, twoBitToFa (available from the kent src tree), can be used to extract .fa file(s) from this file. A pre-compiled version of the command line tool can be found at: http://hgdownload.soe.ucsc.edu/admin/exe/linux.x86_64/ See also: http://genome.ucsc.edu/admin/git.html http://genome.ucsc.edu/admin/jk-install.html rn7.chrom.sizes - Two-column tab-separated text file containing assembly sequence names and sizes. rn7.agp.gz - Description of how the assembly was generated from fragments. rn7.fa.gz - "Soft-masked" assembly sequence in one file. Repeats from RepeatMasker and Tandem Repeats Finder (with period of 12 or less) are shown in lower case; non-repeating sequence is shown in upper case. rn7.fa.masked.gz - "Hard-masked" assembly sequence in one file. Repeats are masked by capital Ns; non-repeating sequence is shown in upper case. rn7.fa.out.gz - RepeatMasker .out file. RepeatMasker was run with the -s (sensitive) setting. February 01 2017 (open-4-0-8) 1.332 version of RepeatMasker RepBase library: Dfam_Consensus RELEASE 20181026 CC RepBase RELEASE 20181026; * rn7.trf.bed.gz - Tandem Repeats Finder locations, filtered to keep repeats with period less than or equal to 12, and translated into UCSC's BED format. est.fa.gz - Rat ESTs in GenBank. This sequence data is updated once a week via automatic GenBank updates. md5sum.txt - checksums of files in this directory mrna.fa.gz - Rat mRNA from GenBank. This sequence data is updated once a week via automatic GenBank updates. refMrna.fa.gz - RefSeq mRNA from the same species as the genome. This sequence data is updated once a week via automatic GenBank updates. upstream1000.fa.gz - Sequences 1000 bases upstream of annotated transcription starts of NCBI RefSeq genes with annotated 5' UTRs. This file is updated weekly so it might be slightly out of sync with the NCBI RefSeq data which is updated daily for most assemblies. upstream2000.fa.gz - Same as upstream1000, but 2000 bases. upstream5000.fa.gz - Same as upstream1000, but 5000 bases. xenoMrna.fa.gz - GenBank mRNAs from species other than that of the genome. This sequence data is updated once a week via automatic GenBank updates. ------------------------------------------------------------------ If you plan to download a large file or multiple files from this directory, we recommend that you use ftp rather than downloading the files via our website. To do so, ftp to hgdownload.soe.ucsc.edu [username: anonymous, password: your email address], then cd to the directory goldenPath/rn7/bigZips. To download multiple files, use the "mget" command: mget ... - or - mget -a (to download all the files in the directory) Alternate methods to ftp access. Using an rsync command to download the entire directory: rsync -avzP rsync://hgdownload.soe.ucsc.edu/goldenPath/rn7/bigZips/ . For a single file, e.g. chromFa.tar.gz rsync -avzP rsync://hgdownload.soe.ucsc.edu/goldenPath/rn7/bigZips/chromFa.tar.gz . Or with wget, all files: wget --timestamping 'ftp://hgdownload.soe.ucsc.edu/goldenPath/rn7/bigZips/*' With wget, a single file: wget --timestamping 'ftp://hgdownload.soe.ucsc.edu/goldenPath/rn7/bigZips/chromFa.tar.gz' -O chromFa.tar.gz To unpack the *.tar.gz files: tar xvzf .tar.gz To uncompress the fa.gz files: gunzip .fa.gz ----------------------------------------------------------------------------- GenBank Data Usage The GenBank database is designed to provide and encourage access within the scientific community to the most up to date and comprehensive DNA sequence information. Therefore, NCBI places no restrictions on the use or distribution of the GenBank data. However, some submitters may claim patent, copyright, or other intellectual property rights in all or a portion of the data they have submitted.
