How did you create PCA? Normally, if you look into single component, it also corresponds to a time frame from where the value has been derived, so you just need to look into both PCs and their corresponding time point in trajectory. It will not be very accurate, but it is very close to the original structure. I hope it should help you.

Thank you, Ayaz Anwar, and I calculated PCA using GROMACS software and visualized the 2D projection of PC1 and PC2.
