Re: [Ecell-users] ecell-3.2.3pre2 AttributeError

[Yasuhiro N. <yn...@sf...>]

Dear Lu,

I'm not a developer but a modeler with E-Cell project.
As you pointed out, both of PythonFluxProcess and PythonProcess in ver 3.2.x don't work correctly at present. E-Cell3 developers work to fix the problems.
Temporarily, I use custom Processes wrote in C++ instead of using Python(Flux)Process.
Some built-in Processes such as MichaelisUniUniFluxProces (/ecell/dm/MichaelisUniUniFluxProcess.cpp) are good samples to develop custom Process.

Regards
Yasuhiro
