QUESTION
I understand the question is not appropriate for this platform, but I can try if I can get some hints,
I've been trying to plot the free energy landscape of a protein structure ("Chignolin"). I'm completely run out of ideas how to do that!! I've MD simulation trajectory file Trajectory file and using pyemma to plot the energy landscape. But I'm getting the error "" TypeError: plot_free_energy() takes from 2 to 20 positional arguments but 28 were given ""
Could someone figure out where the problem lies? Here is my code
...ANSWER
Answered 2021-Feb-10 at 17:53I recommend you start reading the documentation, especially the "learn PyEMMA" section containing Jupyter notebooks teaching you the work-flow to extract properly weighted "pseudo" free-energy surfaces. Usually these surfaces are drawn into the dimensions of the first two slowest dynamical processes, but you can think of any other combination as well. These dimensions are defined by a TICA or VAMP projection, which are basically methods to extract the slow modes from your data, in case of proteins this contains folding and rare events.
As a primer I suggest reading this tutorial first, as it gives you a brief overview how to load and process your data to extract the slow modes. Note that this not yet contain Markov state modelling, so read further in the other examples to learn about that.

Install PyEMMA
You can use PyEMMA like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
