Na mic governance
NA-MIC Governance

Software Sharing:

http://grants1.nih.gov/grants/guide/rfa-files/RFA-RM-04-003.html

  • …software should be freely available …

  • …permit the commercialization of enhanced or customized versions …

  • …include the ability of researchers outside the center and its collaborating projects to modify the source code and to share modifications …


Bsd style license
BSD Style License

  • Open Source

  • No license fees

  • No restriction on use

    • Clinical and commercial uses do not require our permission

  • No guarantees

    • User is responsible for making sure that the software works, we promise nothing. Same for compliance with all regulations.

    • E.g. if you want to use our software for clinical trials, you have to apply for the proper authorizations at your institution
