[Bug-gmx_MMPBSA]: gmx_MMPBSA does not support water/ions molecules in any structure, but we found 113 molecules in the complex

[Premanandabasak]

Bug summary

Hi! I have been encountering this issue recently with the calculation. I have before hand removed pbc conditions and generated no pbc file for the execution of mmpbsa calculation but I am still getting this error.
I have attached the error message below for the reference.
Please help me resolve this.

Hi! have you looked into the structure file? Please give me the required suggestions to overcome this error.

[Valdes-Tresanco-MS]

@Premanandabasak Can you send me the structures using GitHub directly or through Google Drive, One Drive, or any other system? Please don't reply directly to the email because this method doesn't allow attaching any file.

[Premanandabasak]

Here the attached file
complex.zip

[Valdes-Tresanco-MS]

Sorry for the delay.
I don't see any problem with the structure. Can you send me the files you are using to reproduce the problem?
