Dear Mohammad (cc to cig-mc),
Some of your questions have been answered by Eric on CIG-MC mailing list in
May 17. Maybe you are not subscribed to the mailing list? Here is the link

This is described in Chapter 1 of the manual.

I am not sure I understand your question correctly. You can combine the
parameters used in several cookbooks in your model.
For example, if you want to run a regional model with plate history
(cookbook 2) and temperature dependent viscosity (cookbook 3), you can copy
those parameters under [CitcomS.solver.visc] to the cookbook 2 example.

The content of pid files are explained in Section 5.2 in the manual (search
"pid" within the pdf file). The other output data is explained in Appendix
Since the model is in 3d, you will need opendx (or other 3d vis. program)
to interactively visualize the result. The GMT script is for experienced
user to generate publish-quality 2d plot.
