Functionality for handling multi-state models. More...

Detailed Description

Functionality for handling multi-state models.

These are used in IMP to model systems that are found simultaneously in multiple states. For example, a hinge protein may be found in both 'open' and 'closed' forms, and so some experiments conducted on a sample of the protein will return data from both forms. Building a single model that tries to be consistent with all the data will therefore fail - two models need to be constructed.

multi_foxs

Command line tool to enumerate multi-state models with SAXS profiles. See also IMP::foxs for the similar FoXS command line tool.

Standard module functions

All IMP modules have a set of standard functions to help get information about the module and about files associated with the module.

std::string get_module_version ()
 
std::string get_module_name ()
 
std::string get_data_path (std::string file_name)
 Return the full path to one of this module's data files. More...
 
std::string get_example_path (std::string file_name)
 Return the full path to one of this module's example files. More...
 

Function Documentation

std::string IMP::multi_state::get_data_path ( std::string  file_name)

Return the full path to one of this module's data files.

To read the data file "data_library" that was placed in the data directory of this module, do something like

std::ifstream in(IMP::multi_state::get_data_path("data_library"));

This will ensure that the code works both when IMP is installed or if used via the setup_environment.sh script.

Note
Each module has its own data directory, so be sure to use this function from the correct module.
std::string IMP::multi_state::get_example_path ( std::string  file_name)

Return the full path to one of this module's example files.

To read the example file "example_protein.pdb" that was placed in the examples directory of this module, do something like

std::ifstream in(IMP::multi_state::get_example_path("example_protein.pdb"));

This will ensure that the code works both when IMP is installed or if used via the setup_environment.sh script.

Note
Each module has its own example directory, so be sure to use this function from the correct module.
