The Crystallography Source Code Museum contains TMACLE,
a crystal structure refinement program designed for crystals with
twinning by twin lattice symmetry (TLS) (no evidence for
doubling of spots).


Applications were made on 6 documented cases in the period
1989-92. But that program has not evolved and may be considered
as obsolete. It may just be interesting because the source code is
available. It was built from a multi-pattern Rietveld code, changing
the multi-pattern option to a multi twin domain option.
