Hi,

The main issues are here:

These are not the correct namelist variables for aMD. The namelist
variables you want are:

alphad: Dihedral energy alpha value.
ethreshd: Dihedral energy threshold value.
alphap: Potential energy alpha value.
ethreshp: Potential energy threshold value.

There is a mistake in the MDIN for tutorial A22 section 2 (which it
appears you are using). The Amber 14 manual has the correct
information (section 20.2). We will have to correct the tutorial -
thanks for the report.
