Time dependence of PCs
Issue #638
resolved
Hi,
I've been scrolling through the Bio3d archive looking for something on lets say projecting eigenvector back onto each structure in the original trajectory. Can this be done? If so what command should I use?
Many thanks,
Akash

If you are talking about projection of trajectory in the PC space, check out
pca$z
. For example,pca$z[, 1]
gives you time series of trajectory projected in PC1. Hope it helps. -
Thank you for your help, it worked.

To further elaborate, how can I extract the data relating to e.g. PC1, PC2, PC3 so I can plot it against time?
