Detailed Description

Several general purpose optimizers from the GNU Scientific Library (GSL).

The most useful is probably the IMP::gsl::Simplex optimizer. Note that GSL is licensed under the GPLv3, which requires that all other software linked with it also be licensed under a GPL-compatible license.

GSL

The IMP.gsl module requires GSL. It is available as a prebuilt package on all supported platforms. Note that GSL is distributed under the GPL and so cannot be used in C++ applications with certain other dependencies such as CGAL.

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::gsl::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::gsl::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::gsl::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::gsl::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.
