structure=n 1 unknown=error|warning|skip error

Reads an angle file. If there is a Cyana header in the file, the target
function value will be read from the header. Optionally, only the
n-th structure may be read from a multi-conformer file. Otherwise,
all m structures in a multi-conformer file are read and stored as
structures 1,...,m. The first structure read will also be stored in
the default structure memory, 0. The presence of unknown residues or
angles can either cause an error, a warning, or can be skipped.
