Hi ALL,
I am trying to do a PCA for my simulation. I generated a covarience matrix
using g_covar and now I want to visualize the motion only along first
principal component. So with g_anaeig I gave the option "-first 1" "-last
1". But it gave the error as:
--------------------------------------------------------------------------------
Fatal error:
You have selected less than 3 eigenvectors
--------------------------------------------------------------------------------
Cant I generate the projections and filtered trajectories along only one PC?
Please give the entire command line.
You can see projections along 1 PC, don't know about trj filtering.
Any suggestion is welcome. Thanks a lot in advance.
Regards,
Anirban
