Hi,
I am trying to mutate to ARG26 and getting the following error:
randomi_498_> Atoms,selected atoms,random_seed,amplitude: 2031 11 1 4.0000 randomi_496_> Amplitude is > 0; randomization is done. check_inf__E> Atom 206 has out-of-range coordinates (usually infinity). The objective function can thus not be calculated.
Traceback (most recent call last): File "/Users/arjun/script/mutate_model.py", line 157, in <module> optimize(s, sched) File "/Users/arjun/script/mutate_model.py", line 28, in optimize step.optimize(atmsel, max_iterations=200, min_atom_shift=0.001) File "/Library/modeller-9.11/modlib/modeller/schedule.py", line 71, in optimize return o.optimize(atmsel, schedule_scale=self.scale, **vars) File "/Library/modeller-9.11/modlib/modeller/optimizers/conjugate_gradients.py", line 38, in optimize ret = func(self._modpt, mdl.modpt, edat.modpt, libs.modpt, inds, **vars) OverflowError: check_inf__E> Atom 206 has out-of-range coordinates (usually infinity). The objective function can thus not be calculated.
It generates the following 2a01.pdbARG26.tmp file. I notice 7 atoms of the ARG have"0" value on the last column. What does that mean?
ORIGINAL PDB:

The script also gave this error when I am trying to mutate to ARG60. Rest of the ARG and other mutations worked on the model.
Would be helpful if someone could explain the error and how may I fix it.
