schrodinger.application.jaguar.input module

Functions and classes for reading and creating Jaguar input files.

It allows setting and querying of keyword values in Jaguar input &gen sections and also provides an interface to some of the mmjag library.

The JaguarInput class also provides for the running of jobs.

class schrodinger.application.jaguar.input.JaguarInput(input: Optional[str] = None, name: Optional[str] = None, handle: Optional[int] = None, structure: Optional[schrodinger.structure._structure.Structure] = None, genkeys: Optional[dict] = None, reload: Optional[bool] = None, run_kwargs: Optional[dict] = None, text: Optional[str] = None, qsite_ok: bool = False, rename_directives: bool = False, compute_connectivity: bool = True)

Bases: object

A class for specifying Jaguar input.

This is a thin wrapper to the mmjag library and carries very little internal information.

__init__(input: Optional[str] = None, name: Optional[str] = None, handle: Optional[int] = None, structure: Optional[schrodinger.structure._structure.Structure] = None, genkeys: Optional[dict] = None, reload: Optional[bool] = None, run_kwargs: Optional[dict] = None, text: Optional[str] = None, qsite_ok: bool = False, rename_directives: bool = False, compute_connectivity: bool = True)

There are three main ways to create a JaguarInput instance: from a Jaguar input file ‘input’, an mmjag handle ‘handle’, or a Structure instance ‘structure’.

The ‘input’ parameter will provide for initialization and job name from an existing Jaguar input file. (If no new name is provided, calling the save() method will overwrite the original file.)

Note that the structure and name parameters will modify the object status after loading from a file or initialization from a handle has completed. This can be utilized to get the settings from a Jaguar input file but replace the geometry for a new calculation.

Parameters

• input – A jaguar input file; a default name will be derived from the input value.

• name – A jaguar job name that will override the name derived from ‘input’.

• handle – An mmjag handle, pointing to an existing mmjag instance in memory.

• structure – A structure that will populate a new mmjag instance. If specified with ‘input’ or ‘handle’ it will replace any structure provided by them.

• genkeys – A dictionary of keyword/value pairs to set in the input &gen section. If keywords are specified in this mapping and the file, the genkeys value will be used.

• reload – Specifies whether to reload the job from an output file in the run() method. Default value is False, but can be modified by setting JaguarInput.reload to a different value.

• run_kwargs – The run_kwargs dictionary provides default keyword settings for the run function that is called from the launch and run methods. Default is to set no defaults, but this can be modified by setting JaguarInput.run_kwargs to a different value.

• text – The complete text of a Jaguar input file.

• qsite_ok – Allows this class to be initialized from a QSite input file

• rename_directives – When copying directives from an existing input file with relative paths, rename them to match the new input file name.

• compute_connectivity – Whether to compute connectivity for the structure of the read in input. This can be slow for large systems and isn’t needed for most calculations. Default is True. Note QSite inputs will always take their connectivity from the mae file, regardless of this keyword.

reload = False

run_kwargs = {}

launch(*args, **kwargs)

Save the file and launch a job. Returns a jobcontrol.Job object.

Uses the class run_kwargs value as base for keyword arguments to the run function.

run(**kwargs)

Save the file and launch a job with the wait option. Returns a JaguarOutput object. Raises an exception if the job failed.

Set the class (or instance) attribute reload to True to load existing output files of the same name.

save(follow_links: int = 0, validate: Optional[bool] = None)

Write an input file to name.in.

Parameters

• follow_links –

  Flag specifying whether to follow links in the structure to a Jaguar restart file, if present, to append additional sections. Options are:

  • mm.MMJAG_APPEND_OFF: don’t follow links to append additional sections (default)

  • mm.MMJAG_APPEND_OVERWRITE: append sections from link, overwriting any that overlap

  • mm.MMJAG_APPEND_NO_OVERWRITE: append sections from link, not overwriting any that overlap

  • mm.MMJAG_APPEND_X_OVERWRITE: exclusively append sections from link, deleting any already present

  • mm.MMJAG_APPEND_X_NO_OVERWRITE: append sections from link only if no such sections already present

• validate – If True, sections dependent upon geometry, molecular state, basis set are removed if invalid. If not entered (None), default is to validate if “following links”.

saveAs(file: str, follow_links: int = 0, validate: Optional[bool] = None)

Write an input file to name.in and set the object’s name attribute.

Parameters

• file – Filename to use for save file

• follow_links –

  Flag telling whether to follow links in the structure to a Jaguar restart file, if present, to append additional sections. Options are:

  • mm.MMJAG_APPEND_OFF: don’t follow links to append additional sections (default)

  • mm.MMJAG_APPEND_OVERWRITE: append sections from link, overwriting any that overlap

  • mm.MMJAG_APPEND_NO_OVERWRITE: append sections from link, not overwriting any that overlap

• validate – If True, sections dependent upon geometry, molecular state, basis set are removed if invalid. If not entered (None), default is to validate if “following links”.

getSectionText(section: str) → Optional[str]

Return text of section as a string.

Note this does not use mm.mmjag_get_sect_text, which has a small, fixed buffer size of 1024 that can be exceeded by even fairly small sections.

Parameters

section – Name of section to return

Returns

Text of section, or None if section not present

createModifiedGuess(orbital_pairs: List[Tuple[Union[int, str], Union[int, str]]], mixing_angles: Union[List[float], float], restricted: bool = False, delta_scf: int = 0, charge: Optional[int] = None, multiplicity: Optional[int] = None, write: bool = False, suffix: str = '_copy') → schrodinger.application.jaguar.input.JaguarInput

Write a copy of current input file with a modified guess.

This function should be used in scripts to modify the guess of an existing Jaguar input file. To modify a guess from the commandline, use the modify_scf_guess utility script.

Parameters

• orbital_pairs – List of orbital pairs to mix. Optionally specify the spin (a=alpha, b=beta), followed by their absolute index or their index relative to the HOMO (H) or LUMO (L). If spin is not given, it will be assumed to be alpha. For example orbital_pairs = [('aH1','bL2'), (17,18)] would mix the alpha HOMO-1 orbital with the beta LUMO+2 and alpha orbital 17 with alpha orbital 18. Note, HOMO/LUMO refer to the orbitals of the new guess (i.e. with the specified charge/multiplicity)

• mixing_angles – Angle to mix orbitals, in degrees. 90 will simply swap orbitals, while 45 will create an even mixture. Can select a single angle for all pairs or an angle for each pair.

• restricted – Make the new input a restricted spin calculation. An unrestricted calculation is needed for single spin orbital mixing, while a restricted calculation will mix both spin orbitals for each index specified.

• delta_scf – Set the Delta SCF algorithm to use. 0 = Don’t use Delta SCF 1 = Initial Maximum Overlap Method (IMOM) 2 = Maximum Overlap Method (MOM)

• charge – Set the charge for the new input file

• multiplicity – Set the multiplicity for the new input file

• write – Write the new input file.

• suffix – Suffix to append to original filename.

Returns

New JaguarInput object with modified guess.

Raises

• WorkflowValidationError – If charge/multiplicity are inconsistent with the number of electrons.

• JaguarRuntimeError – If the input file doesn’t have a guess or if the number of orbital pairs doesn’t match the number of mixing angles.

getValue(key)

Return the &gen section value for keyword ‘key’.

The return type is as defined by mmjag_key_type().

setValue(key, value)

Set the &gen section keyword ‘key’ to the value provided.

If value is None, the keyword will be unset.

setValues(dict_)

Set multiple &gen section keywords from the provided dictionary

Note that one easy way to specify the dict_ argument is via the "dict(basis='6-31g**', igeopt=1)" syntax for constructing a dictionary.

deleteKey(key)

Remove a key from the &gen section.

deleteKeys(keys)

Remove a list of keys from the &gen section.

getNonDefault()

Return a dictionary of all non-default keys except ‘multip’ and ‘molchg’, which must be retrieved explicitly since they are connected to the geometry.

isNonDefault(key: str) → bool

Has the specified key been set to a non-default value?

Parameters

key – The key to check

Returns

True if the specified key is set to a non-default value. False otherwise.

setDirective(name: str, value)

Set a file specification directive.

getDirective(name: str)

Get a file specification directive.

getDirectives()

Get all file specification directives, except for MAEFILE, which is weeded out by the mmjag function itself.

writeMaefile(filename: Optional[str] = None, structs: Optional[List[schrodinger.structure._structure.Structure]] = None)

Write an associated .mae file and set the MAEFILE directive. If no name is provided, use jobname.mae. If no structs are provided, use self.getStructure().

If an absolute filename is not provided but the input file is known, write the mae file relative to the input file.

If no filename is given and no jobname is set, a random filename will be generated in the current directory.

Parameters

• filename – Name to give the mae file

• structs – A list of structures

getMaefilename(dont_create: bool = False) → Optional[str]

Get the filename of the Maestro file containing the input structure. If no such file exists, it will be created unless c{dont_create} is True.

Parameters

dont_create – If False, a Maestro file will be created if one does not yet exist. If True, None will be returned if no file exists.

Returns

The requested filename as an absolute path. If no file exists and dont_create is True, None will be returned.

Raises

RuntimeError – If no structure is present.

property restart: str

Get the restart name associated with the input file.

getStructure(zmat: int = 0) → schrodinger.structure._structure.Structure

Return a Structure representation of the specified zmat section.

Note that if the JaguarInput instance was created from a Jaguar input file that has no associated Maestro file (MAEFILE), the Lewis structure is determined automatically based on atom distances.

Parameters

zmat – The zmat to return (MMJAG_ZMAT1, MMJAG_ZMAT2, or MMJAG_ZMAT3).

getStructures() → List[schrodinger.structure._structure.Structure]

Return a list of all available structure representations for zmat sections

The first call to getStructure is required because getStructure is guaranteed to return a structure, which might have been set in a different way

setStructure(struct: schrodinger.structure._structure.Structure, zmat: int = 0, set_molchg_multip: bool = True)

Set one of the zmat sections from the provided Structure (or MMCT handle).

If set_molchg_multip is True, calling this method will update the values of molchg and multip. molchg will be consistent with the sum of formal charges in the provided CT, while multip will be set according to the CT-level i_m_Spin_multiplicity property.

Note one may call self.clearAllConstraints() to remove any unwanted constraints or scan-coordinates after updating the Structure. By default, such info will be preserved if the new Structure has the same atoms and connectivity as the original Structure; only XYZs (and charges/multiplicity) will be updated.

Parameters

• struct – The structure to use for setting.

• zmat – The zmat to set (MMJAG_ZMAT1, MMJAG_ZMAT2, or MMJAG_ZMAT3).

• set_molchg_multip – Whether to update molecular charge and multiplicity (default is yes)

hasStructure(zmat: int = 0) → bool

Returns

True if the specified structure is present. False otherwise.

resetStructure(struct: schrodinger.structure._structure.Structure, molchg: int, multip: int, zmat: int = 0)

Redefine the connectivity and formal charges for the input CT, and store the new structure in the current mmjag object, in the &zmat section indicated by the zmat argument.

This function is used when the molecular geometry has changed such that it may not be consistent with its original CT description in terms of bond orders and formal charges, and we want to force the creation of a new Lewis structure.

Parameters

• struct – The structure to use for setting.

• molchg – The value to use for the net molecular charge.

• multip – The value to use for the net molecular spin.

• zmat – The zmat to set (MMJAG_ZMAT1, MMJAG_ZMAT2, or MMJAG_ZMAT3).

Returns

scan count

getScanCoordinate(i: int) → Tuple[int, List[int], float, float, int]

This function returns i-th scan coordinate.

getConstraint(i)

This function returns i-th constraint.

Returns

tuple that contains coordinate type, list of atoms and target value (may be None if constraint is not dynamic). If constraint type is MMJAG_SCAN_CONSTRAINT return None, so that we scan coordinates don’t appear as constraints.

isEquivalentInput(other, thresh: float = 0.1) → bool

Checks whether two JaguarInput instances are describing essentially the same job.

The comparison checks: 1) that the non-default Jaguar keywords are the same 2) that the number of atoms are the same 3) that the structures can be superposed on each other to within a given threshold 4) that all atoms identities (elements and isotopes) are the same.

NB: this means that renumberings of the same structure will be parsed as non-matching. If any of the tests fail, an InputVerificationError is raised (with a message indicating the failed test), otherwise True is returned.
