Dear Amber users

Iam trying to run explicit solvent CpHMD calculations as outlined in
tutorial: http://jswails.wikidot.com/explicit-solvent-constant-ph-md

I managed to get all the output files for the minimization and heating
steps, I tried to run the equilibration step but I cannot get the
*-cprestrt* *.cpin* file form the equilibration step. What could be the

The calculation only produced the following files: .mdout, cpout,.nc and

I used the following commands:

mpirun -np 24 -machinefile $PBS_NODEFILE $exe -O -i md.mdin -p
3LZT.solv10.parm7 -c 3LZT.solv10.heat.rst7 -cpin 3LZT.solv10.cpin -o
3LZT.solv10.equil.mdout -cpout 3LZT.solv10.equil.cpout -r
3LZT.solv10.equil.rst7 -cprestrt 3LZT.solv10.equil.cpin -x
