Citing Octopus

From OctopusWiki
Jump to navigation Jump to search

Octopus is a free program, so you have the right to use, change, distribute, and to publish papers with it without citing anyone (for as long as you follow the GPL license). However, the developers of Octopus are also scientists that need citations to bump their CVs. Therefore, we would be very happy if you could cite one or more papers concerning Octopus in your work.

General Octopus papers

These are the main references about Octopus, you should cite at least one of these in an article that uses Octopus.
