Installation (Debian Linux and macOS)
Ruby, Rails and PostgreSQL
Debian Linux
Uninstall possible pre-installed versions of ruby:
$ sudo apt-get purge ruby
(Re-)install ruby and Rails using rbenv (see here).
Install PostgreSQL and start PostgreSQL server:
$ sudo apt-get install postgresql postgresql-contrib libpq-dev $ sudo service postgresql start
macOS
Install ruby and Rails using homebrew and rbenv (see here).
Install PostgreSQL and start PostgreSQL server with homebrew:
$ brew install postgresql $ brew services start postgresql
Python
Debian Linux
$ sudo apt-get install build-essential python-dev python-pip $ pip install numpy
Check that python version is between 2.7.0 and 3.0.0:
$ python -V
macOS
If not done yet, install Homebrew:
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install python 2.7 with Homebrew:
$ brew install python
Check that python version is between 2.7.0 and 3.0.0:
$ python -V
R
Debian Linux
$ sudo apt-get install r-base-core libnlopt-dev libcurl4-openssl-dev libxml2 libxml2-dev
Open the R environment and check that R version is above 3.2.2:
$ R > R.version.string
macOS
Update XQuartz and Xcode if needed.
Download the R binary from CRAN at https://cran.r-project.org/bin/macosx. Click on the downloaded .pkg file and follow the instructions.
R dependencies
Install required R packages from CRAN and bioconductor:
$ sudo R > install.packages(c("ineq", "rjson", "fpc", "multcomp", "FactoMineR", "colorspace", "vegan", "optparse", "gplots", "fossil", "coin", "SNFtool", "devtools")) > source("https://bioconductor.org/biocLite.R") > biocLite("sva") > library(devtools) > install_github("igraph/rigraph") > q()
Genocrunch web application
Create a new rails project and add the Genocrunch files:
$ rails new genocrunch -d postgresql -B $ git clone https://git@c4science.ch/source/genocrunch-2.1.git /tmp/genocrunch $ rsync -r /tmp/genocrunch/ /genocrunch $ sudo rm -r /tmp/genocrunch $ cd genocrunch \ && cp gitignore.keep .gitignore \ && cp config/config.yml.keep config/config.yml \ && cp config/database.yml.keep config/database.yml \ && cp config/initializers/devise.rb.keep config/initializers/devise.rb \ && cp config/environments/development.rb.keep config/environments/development.rb \ && cp db/seeds.rb.keep db/seeds.rb
Run the install.sh script (this is not essential for the application):
$ chmod 755 install.sh $ ./install.sh $ source .bashrc # or .bash_profile for macOS
The Genocrunch web app will store data files in users/. To store data in another location, use a simlink:
$ rmdir users && ln -s /path/to/your/custom/storage/location users
Ruby libraries (gems)
Use the Gemefile to install required gems:
$ bundle install
Set application configuration variables
Set the application configuration variables in the config/config.yml file to fit the current installation:
#config/config.yml development: # Genocrunch main directory data_dir: /path/to/genocrunch # Additional link(s) that should be included in the Infos menu of the topbar info_links: [{name: 'link_name', href: 'link_url', target: '_blank'}] # Webmaster email webmaster_email: 'webmaster_email' # Send a validation link to user email to confirm registration? user_confirmable: false production: data_dir: /path/to/genocrunch info_links: [{name: 'link_name', href: 'link_url', target: '_blank'}] webmaster_email: 'webmaster_email' user_confirmable: false
Set genocrunch emails
Set the email details that will be used by Genocrunch to send information such as registration confirmation link or password recovery link to users. The following example would set Genocrunch to use an hypothetical gmail address (app_email@gmail.com) in development.
#config/initializers/devise.rb Devise.setup do |config| ... config.mailer_sender = "app_email@gmail.com" ...
#config/environments/development.rb Rails.application.configure do ... config.action_mailer.default_url_options = { :host => 'localhost:3000' } config.action_mailer.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :domain => "mail.google.com", :user_name => "app_email@gmail.com", :password => "app_email_password", :authentication => :plain, :enable_starttls_auto => true } ...
Setup the PostgreSQL server
Create a new role and a new database (you can create different users and databases for development, test and/or production):
$ sudo su postgres # for macOS, replace postgres by _postgres $ psql postgres=# CREATE ROLE myusername WITH LOGIN PASSWORD 'mypassword'; postgres=# CREATE DATABASE my_application_db_name OWNER myusername; postgres=# \q $ exit
Set the config/database.yml file: In development, test and/or production sections, set the database, username and password to fit the corresponding PostgreSQL database. Also make sure to uncomment host: localhost:
#config/database.yml ... database: my_application_db_name ... username: myusername ... password: mypassword ... host: localhost ...
Initialize the database
Two default users will be created: guest and admin. The guest user is required to try the application without registering/signing-in. The admin user is optional. Seting the guest and admin passwords and emails can be done prior to seeding the database, by editing the db/seeds.rb file:
#db/seeds.rb User.create!([{username: 'guest', role: 'guest', email: 'guest@guestmailbox.com', # <- HERE confirmed_at: '2017-01-01 00:00:00.000000', password: 'guest_account_password'}, # <- HERE {username: 'admin', role: 'admin', email: 'admin@adminmailbox.com', # <- HERE confirmed_at: '2017-01-01 00:00:00.000000', password: 'admin_account_password'}]) # <- AND THERE ...
Run the following commands to create and seed the database. Caution: This will erase previous database tables. Use it for installation, not update. For updates, use migrations or SQL queries.
$ rake db:schema:load $ rake db:seed
- Run the Rails server
- Development mode
$ rails server
You can now access the application in your browser at http://localhost:3000 on your machine and your.ip.address:3000 on your network.
By default, the server runs in development mode.
- Start workers
- Prefered way:
$ RAILS_ENV=development bin/delayed_job -n 2 start
OR
$ RAILS_ENV=development bin/delayed_job -n 2 restart
- Alternative way (not recommanded):
$ rake jobs:work
You can now create new jobs (run analysis). Read the documentation (http://localhost:3000/home/doc) for details.
Create a new version
Versions of installed R packages can be referenced in the version page (http://localhost:3000/versions). For this, run the get_version.py script:
$ get_version.py
This will create a .json file in the genocrunch main directory with a name looking like version_2017-12-18_18:03:08.898906.json.
Sign in as admin and navigate to Infos>Versions Click on the New Version button and fill the form. In the JSON field, copy the json string contained in the .json file previously created using the get_version.py script. Finally, click on the Create Version button.
