To help you, I need to see the exact commands that you used. Best is if you can put it all in a script, run the script to be sure that you see the problem, and then copy and paste the script back to this list. Failing that, copy and paste your commands and tell me what your command-line input was to each tool.

Use make_ndx to create a group containing the atoms around which you want
2. trjconv -s a.tpr -f a.xtc -o b.xtc -center tric -ur compact -pbc none
3. trjconv -s a.tpr -f b.xtc -o c.xtc -fit rot+trans
4. run g_spatial on the .xtc output of step #3.
5. Load grid.cube into VMD and view as an isosurface.
I simulated one molecule with water system
1 step i selected solute i.e molecule and totatel system
2 step also same like 1st step
3 step i selected four atoms from molecule and water OW
grid.cube file created and seen in VMD
I am looking for sdf of molecule group and water Oxygen
I am seeing sdf surface and my molecule atoms are overlapping in 3D view
but most of the publication i have seen that there is a distance between sdf
Could you please suggest me how to correct this problem.
thank you very much advance
