Basic usage#

Let’s test standard element names against the recognized topological tiers:

import molsysmt as msm

print('Is "atom" an element?:', msm.element.is_element('atom'))
print('Is "group" an element?:', msm.element.is_element('group'))
print('Is "residue" recognized?:', msm.element.is_element('residue'))
print('Is "custom_tier" an element?:', msm.element.is_element('custom_tier'))

Is "atom" an element?: True
Is "group" an element?: True
Is "residue" recognized?: True
Is "custom_tier" an element?: False
