Hello Modellers users:
I want to analyze a set of PDB models, all with same sequence (84 Aa
peptide) but different conformations (obteined by different methods). So I
used the compare.py script from tutorial to do a first classification from
structure but I get the error:
_modeller.ModellerError: fit2xyz_296E> Number of equivalent positions <
I search this error, and most of the time is related to too different
proteins that do not align well in sequence. But in my case all the protein
are the same sequence!. Even I add a write step between malign() and
malign3d() in the script so I see a perfect sequence alignment.
Some idea? could be the reason that some structures are too different?
