Install the gems
I got started by installing the bio, bioruby gem.

sudo gem install bioruby
sudo gem install bio

I discovered that the bio-graphics gem needs cairo. Here’s how to install it on Ubuntu. This had 50-something dependencies. I just sat back and let them install:

sudo apt-get install cairo-clock cairo-dock-dev libcairo-ruby libcairo2

I also had to install ruby support for pango:

sudo apt-get install -y libpango1-ruby

I installed bio-graphics and the cairo gem.

gem install bio-graphics cairo

George also uses rails_sql_views so I installed this:

sudo gem install rails_sql_views

As George warned in his blog, I had to comment out these lines in

unless Kernel.respond_to?(:gem)
  Kernel.send :alias_method, :gem, :require_gem
end

in rails_sql_views(0.6.1). Mine was located in /usr/lib/ruby/gems/1.8/gems/rails_sql_views-0.6.1/lib/rails_sql_views.rb. I commented out lines 28-30.

Install the biosql_rails_example application

To get george’s app running, I cloned the biorelate repository into my /home/kenglish/workspace directory:

cd /home/kenglish/workspace
git clone  git://github.com/georgeG/biosql_rails_example.git

I edited the database.yml file and added my mysql infomration. You can create the database by hand as George explains but I put in the mysql root username and password in the database.yml file and ran:

rake db:create.

Install the biosql database schema

As George explains, I had to download the biosql schema and untared it. I created the tables like this:

cd /home/kenglish/downloads/
tar xzvf biosql-1.0.1.tar.gz
cd biosql-1.0.1/sql
mysql -uroot -p var_biosql_development < biosqldb-mysql.sql

I put these in the directory biosql-1.0.1/scripts and loaded them with the script load_ncbi_taxonomy.pl.

perl load_ncbi_taxonomy.pl --dbname var_biosql_development  --dbuser root --host localhost --download

I don’t have any bio-related data so I downloaded the following files from the Ncbi ftp site (ftp://ftp.ncbi.nih.gov/pub/taxonomy/): gi_taxid_nucl.dmp.gz taxcat.tar.gz and taxdump.tar.gz.

Now I was able to run George’s Rails app! To be continued…
