Hi,

I found different model for calcium current which comes with a buffering system. Does any reason to have buffering with calcium current?

Good question.

If it works and it does exactly what you want, then it's OK to reuse it. But as a general rule,
it is best to use a modular programming strategy--that is, each voltage- or ligand-gated
current would have its own mod file (or ChannelBuilder), separate from ion accumulation
mechanisms (anything that WRITEs a concentration, such as pumps, buffers, diffusion).
Modular programming makes program development and debugging much simpler, and
allows model components to be reused individually.
