regarding "parameterization of phosphorylated serine " I checked the Martini papers and I couldn't find how it is done. Can somebody please instruct me. In addition in JCTC paper from 2008 I saw that they simulated pentapeptides without imposing secondary structure. How can I do it? The prob

Dear Gromacs users and developers, I'm interested to run simulation of natively unstructured protein (casein), that can self assembly and create micelles, using Martini force field. The initial structure of the monomer was created and minimized using Sybyl. This protein includes also 4 phosp
