Question about freak structures used in prediction testing

1) I wouldn't recommend using any structure with such a poor resolution
(i.e. restrict your data set to those structures that are refined, and
to a resolution of at least 2.5 angstroms or better)
2) 2TMA (Tropomyosin) is not a structure that should be included in an
of any method for prediction of globular protein secondary structures, since it
is not globular.
I would suggest that you have a look through your dataset and remove other
structures having these problems. Nobody would expect such things to
be included in a training/test set, since secondary structure definitions
are often unreliable, making assessment suspect.
