5.25. Utility functions for the TPR topology parser¶

The MDAnalysis.topology.tpr module contains classes and functions on which the Gromacs TPR topology reader TPRParser is built.

5.25.1. TPR support¶

The MDAnalysis.topology.tpr module is required for the MDAnalysis.topology.TPRParser module.

MDAnalysis.topology.tpr.SUPPORTED_VERSIONS = (58, 73, 83, 100, 103, 110, 112, 116)¶

Built-in immutable sequence.

If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable’s items.

If the argument is a tuple, the return value is the same object.

5.25.4. Utilities for the TPRParser¶

Function calling order:

(TPRParser.py call do_mtop)
do_mtop -> do_symtab
        -> do_ffparams -> do_iparams
        -> do_moltype  -> do_atoms  -> do_atom
                                    -> do_resinfo
                       -> do_ilists

                       -> do_blocka
        -> do_molblock

Then compose the stuffs in the format MDAnalysis.Universe reads in.

The module also contains the do_inputrec() to read the TPR header with.

MDAnalysis.topology.tpr.utils.define_unpack_real(prec, data)[source]¶: Define an unpack_real method of data based on the float precision used

MDAnalysis.topology.tpr.utils.do_atom(data, fver)[source]¶

MDAnalysis.topology.tpr.utils.do_ilists(data, fver)[source]¶

MDAnalysis.topology.tpr.utils.do_inputrec(data)[source]¶

Read through header information from TPR file data structure.

Note that this function does not return any useful data itself. If your are interested in using the header information, use this functions as a starting point for your own code.

MDAnalysis.topology.tpr.utils.do_iparams(data, functypes, fver)[source]¶
