Further details and examples

Calculate the RMSD with respect to a reference structure.

The aim of this colvar is to calculate something like:

d(X,X)=|XX|

where X is the instantaneous position of all the atoms in the system and X is the positions of the atoms in some reference structure that is provided as input. d(X,X) thus measures the distance all the atoms have moved away from this reference configuration. Oftentimes, it is only the internal motions of the structure - i.e. not the translations of the center of mass or the rotations of the reference frame - that are interesting. Hence, when calculating the root-mean-square deviation between the atoms in two configurations you must first superimpose the two structures in some way. At present PLUMED provides two distinct ways of performing this superposition. The first method is applied when you use TYPE=SIMPLE in the input line. This instruction tells PLUMED that the root mean square deviation is to be calculated after the positions of the geometric centers in the reference and instantaneous configurations are aligned. In other words d(X,x) is to be calculated using:

d(X,X)=ix,y,zαwijwj(Xi,αcomα(X)Xi,α+comα(X))2

with

comα(X)=iwijwjXi,α

and

comα(X)=iwijwjXi,α

Obviously, comα(X) and comα(X) represent the positions of the center of mass in the reference and instantaneous configurations if the weights w are set equal to the atomic masses. If the weights are all set equal to one, however, comα(X) and comα(X) are the positions of the geometric centers.

An example input that can be used to calculate and print this RMSD distance is shown below:

Notice that there are sets of weights: w and w in the formulas above. The first of these weights is used to calculate the position of the center of mass (so it determines how the atoms are aligned). The second set of weights, w is used when calculating how far the atoms have been displaced. These weights are assigned in the reference configuration that you provide as input (i.e. the appear in the input file to this action that you set using REFERENCE=whatever.pdb). As you can see in the input above, this input consists of a simple pdb file containing the set of atoms for which you want to calculate the RMSD displacement and their positions in the reference configuration. It is important to note that the indices in this pdb need to be set correctly. The indices in this file determine the indices of the instantaneous atomic positions that are used by PLUMED when calculating this colvar. As such if you want to calculate the RMSD distance moved by the first, fourth, sixth and twenty eighth atoms in the MD codes input file then the indices of the corresponding reference positions in this pdb file should be set equal to 1, 4, 6 and 28.

The pdb input file should also contain the weights w and w. These second of these sets of weights, w, appears in the OCCUPANCY column (the first column after the coordinates). These are the weights that are used to calculate the position of the center of mass. The BETA column (the second column after the Cartesian coordinates) is used to provide the w values which are used in the the calculation of the displacement. Please note that it is possible to use fractional values for beta and for the occupancy. However, we recommend you only do this when you really know what you are doing however as the results can be rather strange. A more common practise is to use different sets of atoms for the alignment and the displacement. You can do this by setting the w and w values for all the atoms you wish to use for alignment only equal to zero and one respectively and by setting the w and w values for all the atoms you wish to use for displacement only to one and zero respectively.

In the PDB input files that you use for RMSD the atomic coordinates and box lengths should be in Angstroms unless you are working with natural units. If you are working with natural units then the coordinates should be in your natural length unit. You can find more details on the PDB file format here. Please make sure your PDB file is correctly formatted. More detail on the format for PDB files can be found in the documentation for the PDB2CONSTANT action.

The following input uses a different method to calculate the RMSD distance as you can tell from the TYPE=OPTIMAL on the input line.

In this case the root mean square deviation is calculated after the positions of geometric centers in the reference and instantaneous configurations are aligned AND after an optimal alignment of the two frames is performed so that motion due to rotation of the reference frame between the two structures is removed. The equation for d(X,X) in this case is:

d(X,X)=ix,y,zαwijwj[Xi,αcomα(X)βM(X,X,w)α,β(Xi,βcomβ(X))]2

where M(X,X,w) is the optimal alignment matrix which is calculated using the Kearsley algorithm that is described in the paper from the bibliography below. Again different sets of weights are used for the alignment (w) and for the displacement calculations (w). This gives a great deal of flexibility as it allows you to use a different sets of atoms (which may or may not overlap) for the alignment and displacement parts of the calculation. This may be very useful when you want to calculate how a ligand moves about in a protein cavity as you can use the protein as a reference system and do no alignment of the ligand.

(Note: when this form of RMSD is used to calculate the secondary structure variables (ALPHARMSD, ANTIBETARMSD and PARABETARMSD all the atoms in the segment are assumed to be part of both the alignment and displacement sets and all weights are set equal to one)

The d(X,X) values that are calculated when you use the TYPE=SIMPLE and TYPE=OPTIMAL variants of RMSD are scalars. These scalars tell you the length of the vector of displacements, XX, between the instantaneous and reference positions. If you would like to access this vector of displacements instead of its length you can by using the DISPLACEMENT keyword as shown below for TYPE=SIMPLE

The RMSD command for these inputs output two components

  • dist - the length of displacement vector that is output when you don't use the DISPLACEMENT keyword
  • disp - the 3N dimensional vector of atomic dispacements, where N is the number of atoms.

These vectors of displacements are used if you use the PCAVARS action to compute the projection of the displacement on a particular reference vector.

You can also define multiple reference configurations in the reference input as is done in the following example:

PRINTPrint quantities to a file. More details ARGthe labels of the values that you would like to print to the file=rmsd.disp,rmsd.dist FILEthe name of the file on which to output these quantities=colvar

The RMSD command here still outputs the dist and disp components but now dist is a vector and disp is a matrix. This type of command is used to implement the GEOMETRIC_PATH shortcut. For this command you need information on the distances from a set of reference configurations that can be found in the dist component as well as the information on the displacement vectors between the instantaneous position and each of the reference configurations that is contained in the dist matrix.

Please note that there are a number of other methods for calculating the distance between the instantaneous configuration and a reference configuration that are available in plumed.

A note on periodic boundary conditions

When periodic boundary conditions are used, the atoms should be in the proper periodic image. This has been done automatically since PLUMED 2.5, by considering the ordered list of atoms and rebuilding molecules using a procedure that is equivalent to that done in WHOLEMOLECULES. Notice that rebuilding is local to this action. This is different from WHOLEMOLECULES which actually modifies the coordinates stored in PLUMED.

In case you want to recover the old behavior you should use the NOPBC flag. In that case you need to take care that atoms are in the correct periodic image.

More information about how this action can be used is available in the following articles: - S. K. Kearsley, On the orthogonal transformation used for structural comparisons. Acta Crystallographica Section A Foundations of Crystallography. 45, 208–210 (1989)

Syntax

The following table describes the keywords and options that can be used with this action

Keyword Type Default Description
REFERENCE compulsory none a file in pdb format containing the reference structure and the atoms involved in the CV
TYPE compulsory SIMPLE the manner in which RMSD alignment is performed
NUMBER compulsory 0 if there are multiple structures in the pdb file you can specify that you want the RMSD from a specific structure by specifying its place in the file here
SQUARED optional false This should be setted if you want MSD instead of RMSD
NOPBC optional false ignore the periodic boundary conditions when calculating distances
NUMERICAL_DERIVATIVES optional false calculate the derivatives for these quantities numerically
DISPLACEMENT optional false Calculate the vector of displacements instead of the length of this vector
