Python classes to represent, score, sample and analyze models.
This module contains a variety of high-level Python classes to simplify the construction of a modeling protocol in IMP. One recent use of PMI is the modeling of the Nup84 subcomplex of the nuclear pore complex. Several other applications can be seen at the IMP systems page.
This module is still under heavy development, and should be considered experimental.
See also the PMI changelog.
The objective of PMI is to make it as easy as possible to use the powerful representation, scoring, and sampling tools within IMP (and to add some cool analysis functionality) for common modeling problems. Most PMI classes wrap multiple IMP classes and functions that are commonly combined. While this greatly improves usability, it can reduce flexibility. Let us know if you want to do something not currently supported.
The typical flow of a PMI modeling script is as follows:
Here are some examples to get you started
One can create multiple simultaneous representations in PMI. Here is a brief overview:
