Backmapping - problem with the output structure was created by z.sichaib
Dears,
I'm using the following command to backmap a CG protein to AA:
./initram-v5.sh -f protein_CG.gro -o protein_aa.gro -to amber -p topol.top
The program runs without any issues but when I visualize the AA structure, this last is weird. It looks broken, fragmented into 8 different pieces (?). I don't know if it's a PBC problem or something else. You can see a picture of how the final aa system looks like here: www.dropbox.com/s/smncxffmfz7ztd9/backmap.png?dl=0
I would really appreciate any help/ advice, please.

Does the protein run after backmapping? If so, I guess that you don't have any real issue, it is just that your protein is at the "edge" of the coordinate system (e.g., centered at 0,0,0) and thus gets split in the visualization. Another way to check would be running:
gmx trjconv -f protein_which_looks_split.gro -o whole_protein.gro -pbc whole -s topol-AA.tpr
and try to visualize "whole_protein.gro".
gmx trjconv -f protein_which_looks_split.gro -o whole_protein.gro -pbc whole -s topol-AA.tpr
and try to visualize "whole_protein.gro".
