.. _user-section-repptis:

The REPPTIS and PPTIS sections
==============================

A partial-path simulation reads these settings from the section named
after its task: ``task = "repptis"`` from ``[repptis]`` and
``task = "pptis"`` from ``[pptis]``. Both sections carry the same
keyword. The :ref:`TIS <user-section-tis>` section also has to be
defined for a partial-path simulation.

.. code-block:: toml

    [simulation]
    task = "repptis"

    [repptis]
    memory = 1

The :ref:`shooting_moves <user-section-tis-shooting-moves>` keyword
states which moves a partial-path task accepts.

Keywords for the REPPTIS and PPTIS sections
-------------------------------------------

The following keyword can be set for either section:

.. |repptis_memory| replace:: :ref:`memory <user-section-repptis-memory>`

.. _table-repptis-keywords:

.. table:: Keywords for the REPPTIS and PPTIS sections.
   :class: table-striped table-hover

.. _user-section-repptis-memory:

Keyword memory
^^^^^^^^^^^^^^

.. pyretis-keyword:: memory integer

   Sets the local interface window each positive ensemble samples in.
   With ``memory = m``, ensemble :math:`i` samples the window
   :math:`[\lambda_{i-m}, \lambda_i, \lambda_{i+m}]`, and the paths it
   holds are the partial paths that window bounds. The analysis rebuilds
   the kinetics from the crossing probabilities of these local windows.

   Default
       The default value is ``1``.
