Dear advanced gromacs users,
I have created an arbitrary molecule .gro file containing coordinates of my
martini-beads. basically, there are 50 beads sitting on each axis of (x,y, -x
and -y) forming like a cross. (Each bead with distance 0.43). However, when I
try to use editconf on my .gro file to generate a box (editconf -f star.gro -o
star_box.gro -c -d 1.0 -bt cubic) , it gives me back a new .gro file with a bad
molecule. In VMD viewing, I see that the negative axis part of my molecules are
cut off. Closer inspection shows the following for a particular segment of the
molecule coordinates:
**original .gro coordinates:

Notice the jump on atom number 174 and 175, why is there a sudden coordinate
jump?
All i can see in VMD is my negative axis part of the molecule beads are cut
off.
Any input is appreciated. Thank you!
