============

The automatic computation of moment tensors by :ref:`scautomt` can be triggered
in playbacks or from :cite:t:`scolv` of |scname|.


Explicit triggering in playbacks
--------------------------------

Read the section :ref:`sec-scautomt-playbacks` for starting :ref:`scautomt` explicitely
in playbacks for moment-tensor inversion but also for waveform retrieval.


Implicit triggering by event updates
------------------------------------

The computation is implicitly triggered when committing a new :term:`origin` in
:cite:t:`scolv` that updates the preferred origin of the :term:`event` or that results
in a new event and if the new origin meets the
:ref:`configurable trigger criteria <sec-scautomt-triggering>`.


Explicit triggering from scolv
------------------------------

For explicit triggering the button *Trigger Mw computation*
can be added by configuration to the *Focal Mechanisms* sub-tab of the *Event*
tab in :program:`scolv`.

   Trigger :ref:`scautomt` by pressing *Trigger Mw computation* in the *Focal Mechanisms*
   sub-tab of the *Event* tab in :program:`scolv`.

As :ref:`scautomt` is not available on all |scname| systems this button cannot
be configured by scconfig but must be added to :file:`scolv.cfg`: ::
