Feature dictionary
==================

Use this dictionary to connect exported columns to their calculation.
Names are extracted from current assignments, including tuple assignments;
region-property component families are expanded below. Descriptions draw on
``SingleCellFeatures.xlsx`` and are qualified where its wording differs from code.

Morphology uses unprefixed names with channel ``None``. Other families export
``<channel>_<key>``, such as ``C3_NC_ratio``. Identity columns are documented
in :doc:`data-structures`; correlation columns are in :doc:`../workflow/correlation`.

   features-svm

Array-valued columns remain arrays/lists within one cell row. They are not
separate rows per object. For missing-value interpretation, see :doc:`../workflow/features`
and :doc:`../workflow/objects`.
