I have checked mdcrd file there is theer numbers line not six numbers line after
each snapshot
2.121 -23.199 35.340 36.220 41.041 35.621 35.320 41.209 35.129 36.235
40.108
73.004 73.004 73.004
In restrt file there is six numbers line at the end of file.
I have checked in restrt file 73.004 is box size
-0.1657884 0.4894307 -0.0631572 0.2706823 0.5604288 -0.8288725
-0.6596030 0.8937120 0.1677584
73.0044927 73.0044927 73.0044927 109.4712190 109.4712190 109.4712190
when I removed box size using command
$ awk 'NF != 3' mdcrd > boxless_mdcrd
from mdcrd file and load it to VMD with new prmtop having protein-DNA + 10 water
molecule
again there is same problem i.g. some long bonds formation.
