9VARIABLES: aco_type - CYANA variable

Initial value: 1

The variable 'aco_type' is used to (temporarily) exclude individual
torsion angle restraints from the calculations. It can be used,
for instance, to apply Ramachandran plot restraints only in certain
phases of a simulated annealing schedule (see anneal.cya).

Torsion angle restraints have an integer type assigned to them, which
can be set with the optional type=<integer> parameter of the 'read aco'
command, or for individual restraints within a torsion angle restraint
(.aco) file. The default type value of a torsion angle restraint is 1.
Violations of torsion angle restraints are only considered if its
type value is larger than the value of the variable 'aco_type'.
