@carmine
Great! Thank you for your feedback! -
I'm so sorry Dmitry,
I've ran di NVT again, not the NPT.
I tried again and NPT still doesn't works...Here the log file:

GROMACS stops due to GROMACS warnings. Did you add the -maxwarn option in the additional parameters of this step?
Note, different steps in the GROMACS Wizard (equilibration, simulation, etc) have their own parameters and you may need to specify additional parameters in each one of them.

@DmitriyMarin
Yes, I'm adding -maxwarn option in the additional parameters of Equilibrate menu' after clicking on Isothermal-isobaric (NPT). -
@carmine said in GROMACS wizard - Letal Warning during NPT Equilibration step:
WARNING 1 [file PEP_1_prepared_minimized_nvt_2_boxed.top, line 48]:
The bond in molecule-type Protein_chain_A between atoms 61 OG1 and 62 HG1
has an estimated oscillational period of 9.0e-03 ps, which is less than 5
times the time step of 2.0e-03 ps.
Maybe you forgot to change the constraints mdp option.You may need to solve this GROMACS warning by either modifying the time-step or changing the constraints mdp options.
-
For example, try decreasing the Integration time step to 0,001 ps.

Hi @DmitriyMarin,
now really works!!! The reduction of the time-steps allowed completing the equilibration.
Thank you again!One last question:
If I would like to change the box shape from cubic to rhombic dodecahedron, where can I add the flag -bt dodecahedron? -
@carmine Great!
No, for now, GROMACS Wizard supports only the cubic box type, but we can add other box types in the future releases.
Could you, please, tell us what else you would like to see in the future releases of the GROMACS Wizard or in SAMSON in general?
-
I think that by adding the possibility to choose the box type can be a nice feature, for sure.
In my opinion, another useful feature may be to highlight, in some way, the options that are added into the Additional parameters form, in order to have more clear the extra modifications. -
@carmine Thank you very much for your feedback!
We will add other box types in one of the next updates of the GROMACS Wizard.
Options provided in the Additional parameters have bigger priority then options specified in the GUI. It is true, it would be nice to highlight them in some way.
