+ | Let be your system a complex with a ligand named LIG.\\ | ||
+ | Open a ''ptraj.in'' and add the following lines:\\ | ||
+ | |||
+ | ''trajin rec.all.mdcrd''\\ | ||
+ | ''reference rec.crd''\\ | ||
+ | ''center ~:WAT,Na+,Cl-''\\ | ||
+ | ''image byres :WAT,Na+,Cl-''\\ | ||
+ | ''rms reference mass out rmsREC @CA''\\ | ||
+ | ''rms reference mass out rmsLIG :LIG nofit''\\ | ||
+ | ''atomicfluct out flucREC ~:WAT,Na+,Cl-,LIG byres''\\ | ||
+ | ''rms reference mass out rmsLIGfit :LIG''\\ | ||
+ | \\ | ||
+ | Now enter ''ptraj rec.top < ptraj.in'' \\ | ||
+ | \\ | ||
+ | You should see three different files: ''rmsREC'' (RMSD of Cα atoms of the target), ''rmsLIG'' (RMSD of all atoms of the ligand), ''flucREC'' (RMSD fluctuations of the residues of the target) |
