Thanks Branko and Aron for your suggestions. I've tried before
re-writing the lines and using the "good" .conf from the other mutants,
with no success. I tried it once again and I still have the same memory
error.
I will try Branko's suggestion of using VegaZZ to make sure the PDB file
is correct. Although the PDB file can be read by VMD.
Branko - I've run this simulation in a cluster and in my local machine,
with equivalent results.
I will keep trying...
