## Module: `interfaces.matlab`

Inheritance diagram for `nipype.interfaces.matlab`:

General matlab interface code

## Classes

### `MatlabCommand`

class `nipype.interfaces.matlab.``MatlabCommand`(matlab_cmd=None, **inputs)

  Bases: `nipype.interfaces.base.CommandLine`

  Interface that runs matlab code

      >>> import nipype.interfaces.matlab as matlab
      >>> mlab = matlab.MatlabCommand()
      >>> mlab.inputs.script = "which('who')"
      >>> out = mlab.run()

  `__init__`(matlab_cmd=None, **inputs)

    initializes interface to matlab (default ‘matlab -nodesktop -nosplash’)

  `aggregate_outputs`(runtime=None, needed_outputs=None)

    Collate expected outputs and check for existence

  `always_run`
  `can_resume`
  `cmd`

    sets base command, immutable

  `cmdline`

    command plus any arguments (args) validates arguments and generates command line

  classmethod `help`(returnhelp=False)
  `input_spec`

    alias of `MatlabInputSpec`

  `output_spec` = None
  `raise_exception`(runtime)
  `run`(**inputs)

    Execute this interface.

    This interface will not raise an exception if runtime.returncode is non-zero.

    Parameters : | inputs : allows the interface settings to be updated
    Returns : | results : an InterfaceResult object containing a copy of the instance that was executed, provenance information and, if successful, results :

  classmethod `set_default_matlab_cmd`(matlab_cmd)

    Set the default MATLAB command line for MATLAB classes.

    This method is used to set values for all MATLAB subclasses. However, setting this will not update the output type for any existing instances. For these, assign the <instance>.inputs.matlab_cmd.

  classmethod `set_default_mfile`(mfile)

    Set the default MATLAB script file format for MATLAB classes.

    This method is used to set values for all MATLAB subclasses. However, setting this will not update the output type for any existing instances. For these, assign the <instance>.inputs.mfile.

  classmethod `set_default_paths`(paths)

    Set the default MATLAB paths for MATLAB classes.

    This method is used to set values for all MATLAB subclasses. However, setting this will not update the output type for any existing instances. For these, assign the <instance>.inputs.paths.

  `version`
  `version_from_command`(flag='-v')

  `configure_traits`(filename=None, view=None, kind=None, edit=True, context=None, handler=None, id='', scrollable=None, **args)

    Creates and displays a dialog box for editing values of trait attributes, as if it were a complete, self-contained GUI application.

    Parameters : | filename : string The name (including path) of a file that contains a pickled representation of the current object. When this parameter is specified, the method reads the corresponding file (if it exists) to restore the saved values of the object’s traits before displaying them. If the user confirms the dialog box (by clicking OK), the new values are written to the file. If this parameter is not specified, the values are loaded from the in-memory object, and are not persisted when the dialog box is closed. view : view or string A View object (or its name) that defines a user interface for editing trait attribute values of the current object. If the view is defined as an attribute on this class, use the name of the attribute. Otherwise, use a reference to the view object. If this attribute is not specified, the View object returned by trait_view() is used. kind : string The type of user interface window to create. See the traitsui.view.kind_trait trait for values and their meanings. If kind is unspecified or None, the kind attribute of the View object is used. edit : Boolean Indicates whether to display a user interface. If filename specifies an existing file, setting edit to False loads the saved values from that file into the object without requiring user interaction. context : object or dictionary A single object or a dictionary of string/object pairs, whose trait attributes are to be edited. If not specified, the current object is used handler : Handler object A handler object used for event handling in the dialog box. If None, the default handler for Traits UI is used. id : string A unique ID for persisting preferences about this user interface, such as size and position. If not specified, no user preferences are saved. scrollable : Boolean Indicates whether the dialog box should be scrollable. When set to True, scroll bars appear on the dialog box if it is not large enough to display all of the items in the view at one time.

  `copy_traits`(other, traits=None, memo=None, copy=None, **metadata)

    Copies another object’s trait attributes into this one.

    Parameters : | other : object The object whose trait attribute values should be copied. traits : list of strings A list of names of trait attributes to copy. If None or unspecified, the set of names returned by trait_names() is used. If ‘all’ or an empty list, the set of names returned by all_trait_names() is used. memo : dictionary A dictionary of objects that have already been copied. copy : None | ‘deep’ | ‘shallow’ The type of copy to perform on any trait that does not have explicit ‘copy’ metadata. A value of None means ‘copy reference’.
    Returns : | A list of attributes that the method was unable to copy, : which is empty if all the attributes were successfully copied. :

  `copyable_trait_names`(**metadata)

    Returns the list of trait names to copy or clone by default.

    Displays a user interface window for editing trait attribute values.

    Parameters : | view : view or string A View object (or its name) that defines a user interface for editing trait attribute values of the current object. If the view is defined as an attribute on this class, use the name of the attribute. Otherwise, use a reference to the view object. If this attribute is not specified, the View object returned by trait_view() is used. parent : window handle A user interface component to use as the parent window for the object’s UI window. kind : string The type of user interface window to create. See the traitsui.view.kind_trait trait for values and their meanings. If kind is unspecified or None, the kind attribute of the View object is used. context : object or dictionary A single object or a dictionary of string/object pairs, whose trait attributes are to be edited. If not specified, the current object is used. handler : Handler object A handler object used for event handling in the dialog box. If None, the default handler for Traits UI is used. id : string A unique ID for persisting preferences about this user interface, such as size and position. If not specified, no user preferences are saved. scrollable : Boolean Indicates whether the dialog box should be scrollable. When set to True, scroll bars appear on the dialog box if it is not large enough to display all of the items in the view at one time.
