[gmx-users] Different RMSD plots when either *.gro or *.tpr files are used

[Dawid das]

Dear Gromacs Experts,

I have created two RMSD plots of my protein. For one, as a reference
structure source,
I have used file.gro and in the other a file.tpr, both from previous
calculations. I have obtained
slightly different values and i.e. plots. Is that because my reference
structures where different
or because of different numerical accuracy provided by file.gro and
file.tpr?

Best regards,

Dawid Grabarek
