Dear Modeller Users,

I am currently attempting to generate various mutant models using the MutantBuilder script available at https://github.com/eved1018/MutantBuilder. I have installed Modeller10.5 for this purpose. However, I am encountering the following issue:

python3 MutantBuilder.py -pdb complex.pdb -c B
Traceback (most recent call last):
  File "/home/rehan/Downloads/MutantBuilder-master/MutantBuilder.py", line 372, in <module>

    return func(self.__mdl.modpt, edat.modpt, aln.modpt, io.modpt,
_modeller.ModellerError: getpdf__389E> MDT table range is too small. MDT should be derived with the full range of possible values for the independent variables.

Could someone please assist me in resolving this problem? Your help would be greatly appreciated.

Best Wishes
