That depends on what you are modelling and what you are hoping to observe. There's no substitute for knowledge and learning about the biochemical system of interest, and how other people have approached similar problems, and what they learned. > Also, what are the required necessary things to be edited.

A better approach is to look at published studies similar to the one you propose, to learn from their apparent successes and failures, and to choose tools and methods accordingly. Having chosen tools and methods, it is certain that you will need to spend time reading tutorials, documentation, published articles and asking questions of experts. Indeed, if you can't do this, then you should probably revisit those chocies of tools and methods, or even the proposed study. Mark
