schrodinger.protein.tasks.sta module

class schrodinger.protein.tasks.sta.STATask(*args, **kwargs)

Bases: schrodinger.tasks.tasks.SubprocessCmdTask

output

A Param to represent lists. Values of this param will have a mutated signal that will be emitted whenever any mutation method is called.

The constructor optionally takes a item_class keyword argument to specify what type of class the items in the list will be. This information will be used for jsonifying the list if specified.

class Input(default_value=<object object>, _param_type=<object object>, **kwargs)

Bases: schrodinger.models.parameters.CompoundParam

Variables:
  • query_seq – The sequence to use as the STA query sequence
  • ref_seq – The sequence to use as the STA reference structure
  • constraints – Pairs of (query_seq, ref_seq) residues to constrain
query_seq

Base class for all Param classes. A Param is a descriptor for storing data, which means that a single Param instance will manage the data values for multiple instances of the class that owns it. Example:

class Coord(CompoundParam):
    x: int
    y: int

An instance of the Coord class can be created normally, and Params can be accessed as normal attributes:

coord = Coord()
coord.x = 4

When a Param value is set, the valueChanged signal is emitted. Params can be serialized and deserialized to and from JSON. Params can also be nested:

class Atom(CompoundParam):
    coord: Coord
    element: str

addFuncToGroup(func, group=None, order=None)

Adds a function to the specified chain. Typically used for adding functions that are not methods of this object.

The function may optionally be decorated with a FuncGroupMarker. If so, the default group and order will be determined by the decorator. Any group or order explicitly passed in to addFuncToGroup will take precedence over the decorator settings.

Parameters:
  • func – the function to add
  • group (FuncGroupMarker or None) – the group marker. If the function is decorated with a FuncGoupMarker, that group marker will be the default.
  • order (float or None) – the sorting order. If the function is decorated with a FuncGoupMarker, the order specified in the decorator will be the default.
addPostprocessor(func, order=0)

Adds a postproceessor function to this task instance. If the function has been decorated with @postprocessor, the order specified by the decorator will be used.

Parameters:
  • func (typing.Callable) – the function to add
  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.
addPreprocessor(func, order=-2000)

Adds a preproceessor function to this task instance. If the function has been decorated with @preprocessor, the order specified by the decorator will be used as the default.

Parameters:
  • func – the function to add
  • order (float) – the sorting order for the function relative to all other preprocessors. Takes precedence over order specified by the preprocessor decorator.

processFuncChain(chain=None, result_callback=None)

The result_callback is called after each function with the return value of that function. This can be used to respond to the return value (e.g. present information to the user, get user feedback, log the result, etc.)

The return value of the result_callback determines whether processing will proceeed to the next function.

Parameters:

  • result_callback – the callback that will get called with the result of each function in the chain
Returns:

a list of the results from the functions

reset(*args, **kwargs)
run()
runCmd(cmd)
classmethod runFromCmdLine()
runPostprocessing(callback=None)
runPreprocessing(callback=None, calling_context=None)

Run the preprocessors one-by-one. By default, any failing preprocessor will raise a TaskFailure exception and terminate processing. This behavior may be customized by supplying a callback function which will be called after each preprocessor with the result of that preprocessor.

Parameters:
  • callback – a function that takes result and returns a bool that indicates whether to continue on to the next preprocessor
  • calling_context – specify a value here to indicate the context in which this preprocessing is being called. This value will be stored in an instance variable, self.calling_context, which can be accessed from any preprocessor method on this task. Typically this value will be either self.GUI, self.CMDLINE, or None, but any value may be supplied here and checked for in the preprocessor methods. self.calling_context always reverts back to None at the end of runPreprocessing.
