.. _fwflag_set_min_feat_sum:
====================
--set_min_feat_sum
====================
Switch
======

--set_min_feat_sum N

Description
===========

The minimum total occurrence a feature must have, summed across all groups, to be kept — an alternative/companion to :doc:`fwflag_set_p_occ`'s percentage-of-groups threshold.

Argument and Default Value
==========================

An integer. Default: ``0`` (``dlac.DEF_MIN_FEAT_SUM``) — no filtering.

Details
=======

Marked ``#TODO: Deprecate?`` in the source next to its ``add_argument`` call, for what that's worth. Used together with :doc:`fwflag_feat_occ_filter` and :doc:`fwflag_set_p_occ` — passed as ``fr.createTableWithRemovedFeats(pocc, minfeatsum, groupfreqthresh, ...)``, i.e. both thresholds are applied together when refining a feature table.

Other Switches
==============
