[gmx-users] PCA comparison between two simulations

[francesco oteri]

Dear gromacs users,
I've simulated two different proteins (different atom number) and I carried
out the pca analysis
for the two simulations. Now I'd like to know whether there is a similarity
between the eigenvectors
of the two simulation, i.e. whether the 1st eigenvector of simulation1 is
similar to the 3rd eigenvector
of simulation2. In my case, the eigenvector direction is enough as
definition of similarity.

Can you help me? please
