Hi Sauvik,


see you have errors

*(no leaprc in search path)*

*: not foundpen file leaprc.gaff*


So to me, it seems the path that you are giving to load leaprc.gaff is wrong.

kindly check it.


with regards,

-Abhishek

Subject: [AMBER] Error in LEaP

Hi,

I am trying to generate topology for FAD ligand (Flavin Adenine
Dinucleotide) using Ambertools 16.

So, I generated resp charges after running Gaussian and also generated
frcmod using parmchk. However, as I am trying to run LEaP, it is showing
error. I am using the following code in my leap.in file:

* source /usr/local/amber9/dat/leap/cmd/leaprc.gaff *

* loadamberparams /usr/local/amber9/dat/leap/parm/gaff.dat*

* M = loadmol2 name.mol2*

* mods = loadamberparams frcmod *

* saveamberparm M prmtop inpcrd*

* quit*


However, it is showing error message :


*teLeap -f leap.in <https://urldefense.proofpoint.com/v2/url?u=http-3A__leap.in_&d=DwICAg&c=y2w-uYmhgFWijp_IQN0DhA&r=0Hah93XWYYBgmROOVcaccg&m=jvb-uGD3M_V0oUYsZsUnz64n_v2_ZLQh90py4WweKtY&s=VI_XIuBrayA2XTkzynrApKM1iuu0BhgkVSzNnbg7YlY&e= >*

So, can someone tell me what is the problem with this and how to solve this
out?

With regards,
Souvik
