Thank you.
I'm not sure,too.
Exactly mdrun create md100ns.trr for me, but I'm not sure if any thing is right in the 
So I added -noappend to rerun it again and this result will be correct without doubt. 
By the way, md100ns.trr here mean from 50ns to 100ns.
I just don't want the new run append to md50ns.trr to make me confused.
