Spectral Workbench is an open-source tool to perform low-cost spectral analysis and to share those results online. It consists of a Ruby on Rails web application for publishing, archiving, discussing, and analyzing spectra online -- running at http://spectralworkbench.org

The app now runs on Ruby 1.9.3 up to Ruby 2.1.2 (preferred), and Rails 3.2.x, and uses Bundler for gem management and Bower for static asset management.
Recommended; for an Ubuntu/Debian system. Varies slightly for mac/fedora/etc
Install a database, if necessary:
sudo apt-get install mysql-server
Note: You will have to update the
config/database.yml file appropriately. The example file assumes usage of SQLite. For which you need not install MySQL.
RMagick dependencies are required for processing uploaded spectrum images:
apt-get install imagemagick ruby-rmagick libmagickwand-dev libmagick++-dev
- On Fedora/centOs:
yum install ImageMagick-devel
- On mac, you can use Homebrew:
brew install imagemagick
Install rvm for Ruby management (http://rvm.io)
curl -L https://get.rvm.io | bash -s stable
Note: At this point during the process, you may want to log out and log back in, or open a new terminal window; RVM will then properly load in your environment.
Ubuntu users: You may need to enable
Run command as a login shell in Ubuntu's Terminal, under Profile Preferences > Title and Command. Then close the terminal and reopen it.
Then, use RVM to install version 2.1.2 of Ruby:
rvm install 2.1.2
You'll also need bower which is available through NPM. To install NPM, you can run:
sudo apt-get install npm
However, on Ubuntu, you may need to also install the
nodejs-legacy package, as due to a naming collision, some versions of Ubuntu already have an unrelated package called
node. To do this, run:
sudo apt-get install nodejs-legacy
Once NPM is installed, you should be able to run:
sudo npm install -g bower
- Download a copy of the source with
git clone https://github.com/publiclab/spectral-workbench.git
- Install gems with
bundle installfrom the rails root folder. You may need to run
bundle updateif you have older gems in your environment.
- Copy and configure config/database.yml from config/database.yml.example, using a new empty databse you've created. Do the same thing for config/config.yml file copying it from config/config.yml.example file.
- Initialize database with
bundle exec rake db:setup
- Start rails with
bundle exec passenger startfrom the Rails root and open http://localhost:3000 in a web browser. (For some, just
passenger startwill work; adding
bundle execensures you're using the version of passenger you just installed with Bundler.)
