[gmx-users] Fwd: Command line to obtain multiple eigenvectors

[Ashalatha Sreshty]

Dear Justin,

I did the same before but didnot get the eigenvectors. I am working on
Gromacs-4.5.4.

The actual command line used is as below

g_anaeig_d -f mlecdig-MD-0-202-noPBC.xtc -s mlecdig-MD-1.tpr -v
eigenvec-mlecdig-2-102.trr -eig eigenval-mlecdig-2-102.xvg -n mlecdig.ndx
-proj proj14.xvg -first 1 -last 4 -b 2 -e 102 -tu ns

However, I didnot get all the four eigenvectors in the output file, but
only consisted of the first eigenvector. Sample lines from the output I
pastign it here for your ready reference:

   2.0000    2.89116
    2.0050    3.68519
    2.0100    2.44595
    2.0150    1.92587
    2.0200    2.11691
    2.0250    1.26153
    2.0300    0.98976
    2.0350    1.23497
    2.0400    1.27905
    2.0450    2.31289
    2.0500    1.23402
    2.0550    2.09228
    2.0600    2.20607
    2.0650    2.00745
    2.0700    2.32700
    2.0750    1.98665
    2.0800    2.56843
    2.0850    2.51773
    2.0900    2.86463

Please suggest.

Thank you,
