Hi,
I am trying to set up simulations for KRAS (using PDB id: 5vq2) with tleap. Since the protein comes with Mg ion and GTP, I used the force field for Mg and GTP from this website: http://research.bmh.manchester.ac.uk/bryce/amber. But I got the following error message:
{
/home/kengyangyao/.anaconda2/envs/py36/bin/teLeap: Error!

}
I checked the pdb file, it does not seem to contain atom "CT" so I am a bit confused about the error message, and wonder if anyone have idea what the issue may be and how I could fix it?
Thank you!
Best Regards
