Re[2]: AMBER: rmsd over residues using ptraj

Hi Ty,

    That will align the proteins only based on the marked residue
but not the whole protein. That will cause error.
Best regards,

I suppose you could do it for each residue, one at a time. You can specify the part of the molecule in the mask. For example, you could do something like this:
trajin production.1.mdcrd
trajin production.2.mdcrd
reference average.inpcrd
rms reference mass out rmsdFromAverageResidue1.txt :1 nofit
rms reference mass out rmsdFromAverageResidue2.txt :2 nofit
rms reference mass out rmsdFromAverageResidues3-8.txt :3-8 nofit
