Dear friends,

I have done a pca analysis on a amber trajectory for CA atoms in a protein.
I could load the data with IED plugin. I want to make the arrow
representation to show the eigenvector direction. The IED documentation says
that clicking on an atom help drawing it, but i dnt find any arrow once i
click it. Can anyone please write me how to do this.
