i am using the best conformation of protein ligand file obtained after
docking results

i made the .gro file  by
 pdb2gmx -f pro.pdb -o proceed.gro -water spc -missing -ignh

then the ligand codinates from ligand,gro was obtained from prodrug sever,
then i pasted ligand coordinates in this file
the first three lines are

Gallium Rubidium Oxygen Manganese Argon Carbon Silicon
 2059
  705SER      N    1  -3.373  -1.131   1.295
  705SER     H1    2  -3.442  -1.166   1.232
  705SER     H2    3  -3.339  -1.043   1.261
  705SER     H3    4  -3.298  -1.196   1.303

last three lines are
    1LIG  OAR     33   0.425  -0.911   1.194
    1LIG  CAC     34   0.593  -1.073   1.167
    1LIG  CAT     35   0.500  -1.191   1.198
   9.21266   2.49507   2.95990




and the output for command is
wc -l proceed.gro
2100 proceed.gro
