hi ... when i run grompp i get an error " No such moleculetype Protein " ... i included itp for ACE and AIB after generating them from PRODRG2 server... my top file is :
; Include forcefield parameters #include "ffG43a1.itp" ; Include chain topologies #include "ace.itp" #include "aib.itp" ; Include water topology #include "spce.itp" #ifdef POSRES_WATER ; Position restraint for each water oxygen [ position_restraints ] ; i funct fcx fcy fcz 1 1 1000 1000 1000 #endif ; Include generic topology for ions #include "ions.itp" [ system ] ; Name Protein in water [ molecules ] ; Compound #mols Protein 1 The command i m using is : grompp -f 7eq_w.mdp -c ala.gro -p aquapo_grom.top -o alam.tpr ala.gro is generated using editconf.
