Hi, AMBER Users, I am trying to generate modeling files for a mycobacterial protein containing an iron sulfur cluster. But I am facing issue that my command generates all files (small, standard, and large) except large_mk input file. Below is the shown message and my input file, Iron, and Sulfur mol2 files. Any help in this regard will be greatly appreciated.
Totally there are 81 atoms in the large model.
Totally there are 490 electrons in the large model.
