Number of atoms passed correctly

PLUMED must receive the number of atoms that are being simulated from the MD code in order to calculate CVs correctly.
To test this number is passed correctly to PLUMED we run a short trajectory and output the positions of all the atoms that are passed to PLUMED using the following command:

DUMPATOMS
Dump selected atoms on a file. More details
 
ATOMS
the atom indices whose positions you would like to print out

refers to all the MD codes atoms but not PLUMEDs vatoms. Click here for more information.

Results

Calculations were not sucessful and no data was generated for comparison

The first two columns of the table below contains the number of atoms that were in the structure the MD trajectory started from and the number of atomic positions that were output by the command above. If the PLUMED interface is working correctly these two numbers should be identical.
