Dear all
I want to get a matrix that contains coordinates of alpha carbon atoms of a structure, it mean a matrix like the adjoint picture.
I want to put in each row the coordinates (x y z) of all alpha carbon of a frame of dcd file. I have a dcd file with 100 frames, protein I am using has 50 resids, then I need to get a 100 x 150 matrix. First I aligned ths strtures.
Are there any script for that? Or does somebody have any idea to do that?
Thanks for your suggestions.
