Learn about the Browser

This list is sorted by increasing technical complexity: the first steps require only a webbrowser, the last ones administrator access to a Linux webserver.

Use the browser website

• Video tutorials and slides by Openhelix
• Basic materials written by the gurus: The User's guide and the FAQs.
• A similar page to this one "Learning about the browser"
• View a gallery of browser sessions that highlight interesting data sets.
• Type in (manually) a couple of custom tracks in different formats
• If you need to graph data, there are different graphing formats
• Subscribe to the mailing list or search through it. Most everyday questions have already been asked by someone else so searching gives you an answer usually faster than asking on the mailing list.

Download the data of the genome browser (sequences and annotations)

• Be aware that internal coordinates (not those shown on the website) are 0-based!
• Unlike Gbrowse and Ensembl, UCSC is storing the data partially in SQL (coordiantes, outline of x-y-plots) and partially in flat text files (sequences, alignments, details of x-y-plots)
• Table Browser: The easiest way to access data (you don't have to care whether data is stored in MySQL or in textfiles):
  • Table Browser, File:ISMB2008 UCSC.ppt
• SQL-stored data (FAQ):
  • Public mysql access
  • File:Kent allJoiner.ppt, describes relations between all database tables
  • For all genes-related tables, there is a graphical map (sub-optimal layout :-)
• Flat-file data: Download from the ftp server (stored in /gbdb on browser servers)
  • Text file formats

Install a copy of the browser on your own machine (Unix or Mac)

• Create a mirror of the UCSC site:
  • Official FAQ: mirror a complete browser, the main reference for browser installation
  • Inofficial FAQ: Browser Installation, on the wiki, a lot more info
  • Mirror only selected genomes
  • Adapt your cgi-bin/Hg.conf file for your mirror
  • Be prepared that you'll need to create at least and also download parts of the hg18. At least mouse genomes still depend on it.
  • Updating the data automatically from UCSC
  • Pro and cons of storing custom tracks in MySQL or as flat files
  • How are cookies handled by the browser?
  • Local_tracks_at_mirror_sites
  • The old documentation website with developer documentation

Compile the UCSC source tree and analyze genomes yourself

• • What is the the source tree ?
  • What is documented to be available in the Kent source utilities ?
  • ... and what is really available in the source tree?
  • Some important tools are already compiled (even for windows!) from here
  • Compile all tools (includes the browser webserver) yourself
  • The best starting point is the main zipfile: http://hgdownload.cse.ucsc.edu/admin/jksrc.zip
  • You need to set some environment variables before you start the compilation
  • Walkthroughs for...
    • MacOS X users
    • Debian and Ubuntu
    • CentOS Notes
    • Windows: see [1] but your mileage may vary to get everything to compile.

• • The most common problem on the mailing list are harmless warnings that trigger errors. "cc1: warnings being treated as errors". To ignore them, which is usually safe, remove the -Wall option from the makefile
  • See also the textfile README.building.source README.building.source
  • Search through the archives or the Technical-FAQ-Category of the wiki when you have problems
  • Send an email to the mailing list if you cannot find the answer yourself
  • Some more sophisticated genome pipelines
    • Create your own whole-genome alignment
    • Create your own liftOver file

Modify your own copy of the browser

• Add tracks to your own mirror:
  • Charles Sugnet's presentation about TrackDB
  • How_to_add_a_track_to_a_mirror
  • The structure of the trackDB
  • List of trackDB statements
  • Examples: UCSC trackDb for hg19
  • When you run into problems, search through the mailing list when you have problems and read the documentation in the directory kent/src/product
  • color codes
  • a similar place with hgSearchSpec docs and statistics (the system to search for ids) can be found completely off-track
• Create a browser for a completely new genome

Making Of: How the UCSC genome annotations are created

• How the UCSC folks created their tracks:
  • The UCSC's makeDb-files are a log of all commands that are necessary to re-create all annotations for a particular genome.
  • Some explanations how to read the makeDb files: bashVsCsh
  • Notes on the history of the internal tools: Autosql. Blastz. Chains and nets
• Whole-genome multiple alignments (Chains_Nets)
  • Mm9_multiple_alignment
  • Whole-genome alignment pipeline: Angies mental model and Max's howto
• How to create a browser for a new genome from scratch
• Genbank Updates

Developing with the UCSC API

• Debug the cgi-scripts with GDB
