[gmx-users] PCA multiple outputs from g_anaeig

[Sridhar Acharya]

Hello,

g_anaeig analyzes the eigen vectors from eigenvec.trr and eigenval.xvg 
generated by g_covar and writes the proj.xvg, 2d_proj.xvg, 3d_proj.xvg, 
filtered.xvg..... etc.
My question is.,
For a single run of g_anaeig only a specific 2d_proj.xvg (say between 
eigenvec 1 and 8), 3d_proj.xvg..... etc could be written. But one may 
want to study the projections between 1 and 2, 1 and 3, 2 and 3..... etc.
Is there any way to simultaneously write all the desired projections and 
filtered trajectories from a single run of g_anaeig, since all the 
required information will be already read once by the program. Any 
contributors for this?

Thanks in advance.
