Dear Amber Users,

* When I read my MDCRD file in CPPTRAJ, it shows that it's reading 18 of
1750 frames.

 0: 'prod_noW.mdcrd' is an AMBER trajectory, Parm native_nowat.top (reading
18 of 1750)
  Coordinate processing will occur on 18 frames.

My mdcrd file actually contains 245,755 frames as per the following email:

* When I TRAJIN my mdcrd file, I got the following warning:

Warning: Trajectory only contains box lengths and topology has no box info.
Warning: To set box angles for topology use the 'parmbox' command.

So, apparently my topology file doesn't have box information but my
trajectory file has box coordinates. Should I skip reading the box values
from trajectory file? If so, Can can I do it. And, I would like to know if
there is a way to understand why it reads less number of frames. Can
someone help me with this?
