Hi David,

after reading the man page of g_traj and some tests on its output, I can
not discover a way of getting the total mass of an index group (e.g.
protein).


The total mass of the protein is printed by pdb2gmx. Otherwise you can process your topology using a Perl script (or something similar) to tally up the entries in the mass column.

Hi users!

Is there a gmx tool, which calculates the mass of one or more index
groups? The manual says something about a tool named "g_com", but it
seems, as if it does not belong to gmx4.0.3 anymore.
try g_traj

Greetings,
Christian.
