This page contains links to sequence and annotation downloads for the genome assembliesfeatured in the UCSC Genome Browser. Downloads are also available via ourJSON API, MySQL server,or FTP server.Data filtering is available in theTable Browseror via the command-line utilities.

The following location has assembly sequences used in alignment tracks, such as in the 100-species conservation track. For example, you can find the underlying mayZeb1.2bit sequence file for the Zebra Mbuna fish assembly, not yet released but used in the hg38 Vertebrate Multiz Alignment & Conservation (100 Species) track, here: These links also display under a column titled "UCSC version" on the conservation track description page.

The /gbdb fileserver offers access to all files referenced by the Genome Browser tables, with serversin North America andEurope for faster downloads.Many files in the browser, such as bigBed files, are hosted in binary format. For example, in the hg38 database, thecrispr.bb and crisprDetails.tab files for the CRISPR trackcan be found using the following URLs: North American server: European server: -euro.soe.ucsc.edu/gbdb/hg38/crispr/ Individual regions or whole genome annotations from binary files can be obtained using toolssuch as bigBedToBed, which can be downloaded as a precompiled binary for your system (see the Source and utilities downloads section). The bigBedToBed tool can also be used to obtain aspecific subset of features within a given range, e.g.:

I you need to download sequences, first you need to tell the website the coordinates that you want to download. (Remember that table browser is for batch processing). Click on "Custom track" and type in something like this:

The advantage of this procedure is that you can request thousands of sequences in one go. No need to use an API. For scripting see my reply above that uses the linux command line tool "twoBitToFa" from UCSC.

I think, now UCSC browser has changed. Even I have the same query, but unable to fetch FASTA sequence using the coordinates. Can u explain using the given link.. -bin/hgTables?hgsid=703655381_NWHqxkgVDaPPscUhaKxyA9bAbb7e

Genome 10K is a project to sequence the genome of at least one individual from each vertebrate genus, approximately 10,000 genomes. It is a key milestone on the way toward the Vertebrate Genomes Project, the project to find and sequence at least one individual from each of the approximately 66,000 vertebrate species.

The CSE Department has restructured the entire lower division programming sequence, shifting from Java to Python, and changing the prerequisite structure to give students a stronger programming foundation. The Department is phasing out current introductory programming courses and introducing new courses.

During spring quarter, UC Santa Cruz faculty members Ed Green and Kevin Karplus will lead a team of graduate students in assembling the genome sequence and annotating the data collected from the sample. This will make the information more accessible and allow researchers to analyze the extensive quantity of information.

The news has been filled with stories on the new variants of SARS-CoV-2, the virus that causes COVID-19. The UC Santa Cruz Genomics Institute is leading an effort in Central California to sequence the virus and make information available about the strains present in California to the broader scientific and health community.

The iGenomes are a collection of reference sequences and annotation files for commonly analyzed organisms. The files have been downloaded from Ensembl, NCBI, or UCSC. Chromosome names have been changed to be simple and consistent with the download source. Each iGenome is available as a compressed file that contains sequences and annotation files for a single genomic build of an organism.

There are numerous algorithms available as freeware or by public access in the cloud that make complex biological sequence analyses accessible to everyone. This self-paced, introductory course, aimed at professionals who want to break into the sequencing-related field of bioinformatics, explores important public access tools used for analyzing biological sequence data.

Through hands-on examples and exercises, you will learn how to access public databases for raw sequence data and perform the basic steps in processing next-generation sequence data for RNA, DNA, and ChIP sequencing data to obtain interpretable results.

As vertebrate genome sequences near completion and research refocuses to their analysis, the issue of effective genome annotation display becomes critical. A mature web tool for rapid and reliable display of any requested portion of the genome at any scale, together with several dozen aligned annotation tracks, is provided at This browser displays assembly contigs and gaps, mRNA and expressed sequence tag alignments, multiple gene predictions, cross-species homologies, single nucleotide polymorphisms, sequence-tagged sites, radiation hybrid data, transposon repeats, and more as a stack of coregistered tracks. Text and sequence-based searches provide quick and precise access to any region of specific interest. Secondary links from individual features lead to sequence details and supplementary off-site databases. One-half of the annotation tracks are computed at the University of California, Santa Cruz from publicly available sequence data; collaborators worldwide provide the rest. Users can stably add their own custom tracks to the browser for educational or research purposes. The conceptual and technical framework of the browser, its underlying MYSQL database, and overall use are described. The web site currently serves over 50,000 pages per day to over 3000 different users.

In addition to these tables, the database includes several non-positional tables that contain auxiliary data related to the mRNA sequences, e.g. DNA sequence, organism, or author. This information supplements the details pages for individual features in the graphical browser, but is not used in the display.

UCSC generates several annotations based on mRNA alignments. The mRNA and EST sequences are extracted from GenBank, and are aligned against the genome using the BLAST-like Alignment Tool (BLAT), a fast sequence alignment tool developed by Jim Kent (4). The data is filtered based on percentage identity and near best in genome to select only those alignments that best match the sequence. The spliced EST annotation is computed from the filtered data by analyzing the EST alignments for evidence of splicing.

The Genome Browser menu bar provides access to the BLAT search tool, the DNA sequence underlying the features in the annotation tracks graphic, a coordinate conversion tool for locating the position of a feature in a different release of a genome, and user documentation. The menu bar also contains direct links to the complementary annotation in the Ensembl Genome Browser and NCBI's Entrez MapView.

The Downloads link on the UCSC Genome Bioinformatics home page offers a convenient interface for downloading current and archived sequence and annotation data. Data can also be downloaded via ftp at Zipped data for each genome assembly is organized into three folders. BigZips contains the sequence data, which is packaged by chromosome and by contig. Files ending in suffix .fa contain the sequence in Fasta format for the contig layout. Files with suffix .agp contain an index that shows how the corresponding .fa file is built, with each line representing an actual sequence record or a gap. The Chromosomes folder contains the assembled sequence in Fasta format divided up by chromosome. The Database folder contains the genome annotation database tables in tab-delimited format.

The UCSC Genome Browser is an online graphical viewer for genomes, a genome browser, hosted by the University of California, Santa Cruz (UCSC). The interactive website offers access to genome sequence data from a variety of vertebrate and invertebrate species and major model organisms, integrated with a large collection of aligned annotations. This dataset is a copy of the MySQL tables in MyISAM binary and tab-sep format and all binary files in custom formats, sometimes referred as 'gbdb'-files. Data from the UCSC Genome Browser is free and open for use by anyone. However, every genome annotation track has been created by an academic research group, or, in a few cases, by commercial companies. Please acknowledge them by citing them. The information can be found by going to , selecting the respective genome assembly and clicking on the data track. At the end of the documentation, we provide a list of references and acknowledgements. 17dc91bb1f
