Hi, all

1dx0.pdb during MD step at 19532ps are broken into 8 fragments, as VMD show
about  bovin19532.gro

   <http://gromacs.5086.x6.nabble.com/file/n5009221/aa.jpg>

as picture shows that  at the bottom the number of protein is 8

while when I use VMD to see md_0_1.gro the last structure of MD finished

<http://gromacs.5086.x6.nabble.com/file/n5009221/bb.jpg>

at the bottom the number of protein is 1

So, it seems from last structure it can not tell if is this protein broken.

Is there anyway to check if protein  is broken during MD?


By definition, bonds cannot break or form during MD. Therefore, your protein can't possibly break apart. What you're seeing is the effect of periodic boundaries. In the trajectory, mdrun writes "broken" configurations that are easily accounted for using trjconv (see the manual). For convenience, the final snapshot is always written such that it is properly rebuilt.
