connection_test¶
This test queries for the presence or absence of covalent bonds.
The general interresidue test type will count the number of
covalent bonds between atoms on different residues within the
stipulated selection. The disulfide test specifically tests
for interresidue bonds between atoms named SG in residues named CYS.
The glycosylation test will count the number of bonds between
ND2 atoms in the selection and C1 atoms outside the selection.
Single-valued attributes:
name: User-selected name of this connection test
selection: VMD atomselection string defining the selection to be tested
connection_type: The type of connection to validate; interresidue, disulfide, or glycosylation
connection_count: The expected number of connections in the selection
