[gmx-users] PCA

[pawan raghav]

I have done PCA using first g_covar and got eigval.xvg and eigenvec.trr
files. The eigenvectors were analyzed by g_anaeig program and got
eigcomp.xvg, eigrmsf.xvg, proj.xvg, and 2dproj.xvg files. Then I want to
know
1. Which file among these shows relative positional fluctuation with
eigenvector index.
2. Probability distributions for the displacements along several
eigenvectors.
3. Absolute values of the projections of the (normalized) extracted vectors.
4. Cumulative percentage of the motion  of a protein from eigvalues.xvg file
