What do I do when software is not available in the Ubuntu software center?
For instance, I cannot find programs like Netlogo, FIJI (although ImageJ is available), or Copasi.
All I manage to do is download the files, extract them to my home folder (i.e. programs are not available globally), and open the program from this folder. Then, however, no icon is automatically added to my applications (and I don't know how to do that manually). To me, this does not seem like an elegant workflow to install software. Is there a better way?
Thanks for the help.
