Improve Usability with SBML models

[shoepfl]

Dear SBGN team,

i wanted to use SBGN for the first time and tried to convert my SBML model. However, I encountered several pitfalls that made it impossible for me:

1. The link for the only converter tool on the website does not work and i cannot finde the tool on google
2. I tried CellDesigner but it does not support SBML Level 3.1 - The problem is that libsbml does not like to save my model in 2.X directly without changes. The SBFC converter only says that the functionality SBML2SBML conversion cannot be found so this is also not an option. So CellDesigner is also very hard to use.

In my opinion there should be made several improvements in the documentation so that the conversion can be done without running into many pitfalls and then give up frustrated as I personally like the idea of SBGN very much.

Is there currently a way to handel a SBML level 3 file?

Best, Sebastian
