Conversion DESMOND--> AMBER

[icamps]

I would like to know how to make the conversion DESMOND-->AMBER.

From here, it is tell that the conversion will be DESMOND--> GROMACS --> AMBER.

Using the command:

python convert.py --des_in ~/Documents/01_Sim1-ARB/desmond_md_Sim1-ARB-out.cms --amber --odir ~/Documents/AMBERFormat/01_Sim1-ARB/

I am getting the message:

ERROR 2020-08-18 16:17:04 list index out of range
Traceback (most recent call last):
  File "convert.py", line 663, in _save_amber

    atoms = [molecule.atoms[int(w)-1] for w in line.split()]
IndexError: list index out of range
INFO 2020-08-18 16:17:04 Finished!

and two files are created:

desmond_md_Sim1-ARB-out_converted.top
desmond_md_Sim1-ARB-out_converted.gro

What I am doing wrong? I appreciate any help.

So, it's converting Desmond into GROMACS correctly, but not from GROMACS into AMBER. So there is probably something wrong with the GROMACS files. It's impossible to tell from here, though. How many atoms are the .cms files?

[icamps]

In the .cms file are 89531 atoms.

Any ideas?

Do you have sample files? It's hard to debug with out sample files to run to replicate the error.

The files are too big (2.4GB) to share here. Please, you can download the DESMOND files from https://bit.ly/3lBOYzY.
