Hello,
I would like to calculate the dot product between eigenvectors from two separate PCA on the same protein.
I found these instructions:
* Load both sets of modes: load traj1.nc, load traj2.nc.
* Use vectormath to calculate the dot product or angle. For example, to compare the first mode of each set:
vector v1 = modes1[1] // First mode from modes1.nc
vector v2 = modes2[1] // First mode from modes2.nc
vectormath vec1 v1 vec2 v2 dotproduct [out dot1.dat]
It all makes sense in principle, except for the definitions of the vectors (the = sign). How do I equate vector v1 with the first eigenvector?
