Here you are saying each frame represents 0.2 ps of time...

You read in 3598 frames; the first trajectory contains only 398 frames.

You should get a RMSd data file that contains 3598 lines of text (one
value per each frame) which can be checked via "wc -l *.rms"

Let me know if there is still a problem you do not understand.
