Periodic Sequence Split Table
=============================

.. image:: sequencesplit.svg
   :width: 48


Splits tables of data in equidistant points based on the periodicity of an identifier column



**Documentation**

Find peaks in a signal and slice the input Table into a list of Tables, where
each element contains one peak.

If peaks are found very close to the edges of the data, the first and/or
last element may contain unexpected results. If this is the case,
use :ref:`Slice List` to remove these elements.


**Definition**


*Input ports*

    :sequence:  table

        The sequence to split


*Output ports*

    :sequences:  [table]

        The split sequences



*Configuration*:
    **Peak Detecting Algorithm** (peak_detector)
        Choose which algorithm to detect periodic events
    **Samples per peak** (samples)
        Choose an approximate value for the number of expected samples between peaks
    **Select column:** (select_column)
        Choose column to use as identifier
    **Offset of peridodic event(0-100)** (lag_offset)
        Add lag as a percentage of the discarded data
