There is use for it. It is actually a very convenient way to initialize
conformation in any folding orloop modelling/reconstruction experiment that
you want to do. Or if you want to develop modelling codes that are not just
We tried to prototype a folding code on top of MMTK and the first thing we
had to do was to write a kludge to generate an extended conformation from a
protein sequence. If it will ever leave the kludge state i may send it back
to konrad to be considered for inclusion in MMTK. However if someone will
submit earlier a consistent general-purpose conformer generator for
sequences, i will be happy to throw away mine.
