Hello,
I have a problem with cpptraj. I installed it locally on my computer via the conda AmberTools installation method, which is provided on the Amber website.
The cpptraj program seems to start fine, but when I try to load a trajectory after loading the parameters file (psf or pdb) it says that there is an error in the number of atoms in the parameter file and in the trajectory.
Error: # atoms in DCD file (93892) does not match # atoms in parm step5_assembly.psf (93854)
Error: Could not set up 'blabla.dcd' for reading.
Error: Could not set up input trajectory 'blabla.dcd'.
The same parameter file+trajectory works fine on a HPC install od amber-18-gcc, in addition it works fine with Charmm, Namd and VMD. So in reality there isn't a mismatch between the two.
On the HPC I like to use cpptraj very much, it is very fast and would like to use it also on my local computer.
So there must be something wrong with the install/configuration of cpptraj on my local computer.
I tried both the Ambertools version 20 and 19, same behaviour.
Can you help me?
Regards,
Marko
