Dear Users!!


 I have a question about RMSD.  I ran MＤ simulaton for 500ns and connected
all my .xtc files using trjcat command.
And , then I used g_rms command with the connected .xtc file to calculate
RMSD for backbone atoms. But , when I run g_rms command , I get a warning
as follows:



WARNING: If there are molecules in the input trajectory file
         that are broken across periodic boundaries, they
         cannot be made whole (or treated as whole) without
         you providing a run input file.

Can someone say , why this warning msg is coming, and how should i need to
avoid this. what measure should i need to take ?




Thank you.
