The obenergy tool can be used to calculate the energy for molecules inside (multi-)molecule files (e.g., MOL2, etc.)
If no filename is given, obenergy will give all options including the available forcefields.
Verbose: print out all individual energy interactions
- -ff forcefield
Select the forcefield
View the possible options, including available forcefields:
Calculate the energy for the molecule(s) in file test.mol2:
Calculate the energy for the molecule(s) in file test.mol2 using the Ghemical forcefield:
obenergy -ff Ghemical test.mol2
Calculate the energy for the molecule(s) in file test.mol2 and print out all individual energy interactions:
obenergy -v test.mol2
