SequenceServer lets you rapidly set up a BLAST+ server for individual use or for sharing datasets with colleagues and community. Its minimalist, modern and thoughtful design lets you focus on the Biology and getting things done. SequenceServer is free and open source.

SequenceServer has been used for research on emerging model organisms (e.g., sea cucumber, starfish, falcons, Hessian fly, sugar-apple tree, Streptocarpus rexii), and for research in bioadhesion and environmental microbiology. SequenceServer is a main querying mechanism for several community databases (e.g., Drosophila suzukii, planarians, birch and ash tree, Amborella, echinoderms, Fusarium, ants, butterfly), and is also used as an educational resource .

  • Automatic detection of BLAST software - if absent the correct version is automatically downloaded.
  • Detects existing BLAST databases and automatically lists them in the search interface.
  • Detects sequence type of FASTA files and prompts to turn them into BLAST databases.
  • Built-in web server for light to medium usage. Can be integrated with Apache / Nginx if required.
  • Easily add custom links to search hits (e.g. to a genome browser or a page describing the sequence).
  • Type or paste query sequences, or drag-and-drop a FASTA file to search.
  • Smart user interface automagically figures out the appropriate BLAST method for the given query and selected databases.
  • Use advanced parameters as you would in the command line: -evalue 1.0e-10 -max_target_seqs 10
  • Graphical overview of results naturally separates strong from weak hits (by evalue).
  • GenBank style visualisation of hit sequences - residues grouped in multiples of five.
  • Download hit sequences in FASTA format, and alignment data in tab-delimited and XML format for further analysis.
  • Step-by-step discovery of workflow and options through interactive, visual feedback.

Setup process.

Screenshot: Setup process

  • Linux or Mac OSX. While we would like to also support Windows, our resources are limited and we prefer to first concentrate on making SequenceServer great on fewer platforms. It should be possible to run SequenceServer on Windows using Cygwin. Note that you can connect to SequenceServer running on other machines from your browser in Windows.

  • Ruby (≥ 1.8.7) along with the ruby-dev package on Darwin/Debian. NCBI BLAST+ (≥ 2.2.30+) is interactively downloaded if absent.

  • Google Chrome or Mozilla Firefox or Safari 7+ or Internet Explorer 9+

Run the following in a terminal to install, configure and run the latest release of SequenceServer. It will automatically guide you through an interactive setup process to locate or download BLAST+ binaries, ask for the location of FASTA files (or BLAST+ databases), and offer to create BLAST+ databases from FASTA files.

# Install or update.
sudo gem install sequenceserver

# Configure and run.

Alternatively, you can use SequenceServer with Docker - only need to specify the location of your database directory.

docker run --rm -itp 4567:4567 -v /path-to-database-dir:/db wurmlab/sequenceserver

That's it! Open http://localhost:4567/ and start BLAST-ing!
