I think all is OK; I need to update the output from ptraj here. As far as
coordinates go, 574 atoms were found which matches your PDB so all is OK.
The extra are probably other lines in the PDB file (such as REMARK, TER,
etc). That error/warning message should not be printed when the number of
coordinates matches the number of atoms i.e. when 574=574 (i.e. I was
probably checking the loadPdb return value to the number of atoms
incorrectly/inaccurately).
