Not true free and open source projects

The following projects have unknown licensing, licenses which place some restriction on use or redistribution, or depend on non-open-source software like MATLAB, and therefore do not meet the Open Source Definition from the Open Source Initiative. (For example, the license may rule out use by certain people or for certain purposes, e.g. in a commercial context.) They are included here because they may be of interest for those in an academic environment or access to tools like MATLAB.
