docker run -i -t -p 8080:80 bgruening/galaxy-blast
For more details about this command line or specific usage, please consult the
README of the main Galaxy Docker image, on which the current image is based.
Reproducibility of your search results
BLAST databases are updated daily and are not versioned. This is a general problem for reproducibility of search results.
In Galaxy we track the program version, all settings and the input files. The underlying database can be tracked but this is usually
very storage expensive. Note that the large NCBI BLAST databases exceeds 100 GB in size.
To enable 100% reproducibility you can simply create your own BLAST datbase with Galaxy. Download your database as FASTA file
and use the tool
NCBI BLAST+ makeblastdb to convert your FASTA file to a proper BLAST database. These steps are reproducibly, with all settings and inputs.
If you want to use the precalculated BLAST databases from the NCBI FTP server you can
configure your BLAST Galaxy instance to use those. Please have a look at Using large external BLAST databases. We have plans to make this a lot simples by using Galaxy data managers. You can track to progess here: https://github.com/peterjc/galaxy_blast/issues/22
Please understand that we cannot ship the NCBI BLAST databases by default in this Docker container, as we try to keep the image as small as possible.
Using large external BLAST databases
You can get BLAST databases directly from the NCBI server and include them into your Galaxy docker container.
- Download your databases from ftp://ftp.ncbi.nlm.nih.gov/blast/db/.
You can use the NCBI suggested perl script to automatize this step.
- Store all your BLAST databases in one directory, for example
- Start your Galaxy container with
-v /galaxy_store/data/blast_databases/:/data/to have access your databases inside of your container.
- Start your Galaxy container with
-v /home/user/galaxy_storage/:/export/to export all config files to your host operating system,
- Modify your
/home/user/galaxy_storage/galaxy-central/tool-data/blast*.locon your host, or under
/export/galaxy-central/tool-data/blast*.locfrom within your container.
- You need to add the paths to your blast databases. A path points to the BLAST databases accessible from within Docker and looks like
- Restart your Galaxy instance, for example with
docker exec <container name> supervisorctl restart galaxy:
From now on you should see predifined BLAST databases in your Galaxy User Interface if you choose
Locally installed BLAST database.
