Hi all
It's my first message so pleas be forgiving for my mistakes and for my
English because it's not very good.
I'm not advance user of NAMD but I also not so newbie.
I tired to do simulation of protein with NAG (stand alone - not connected)
but I have a problem with that and I can't find solution in Internet
and I also don't have anyone who can help me.
when I tired to run NAMD I have error:
------------- Processor 0 Exiting: Called CmiAbort ------------
Reason: FATAL ERROR: DIDN'T FIND vdW PARAMETER FOR ATOM TYPE CPS
Fatal error on PE 0> FATAL ERROR: DIDN'T FIND vdW PARAMETER FOR ATOM TYPE CPS
----------------------------
my psfgen look fine and work without problem (I found in Internet to
replace CPS to CT3):
after that I have another error after runing NAMD:
FATAL ERROR: CAN'T FIND BOND PARAMETERS FOR BOND CT3 - CTS IN PARAMETER FILES
-------------------
my psfgen file:
topology top_all22_NAG.inp
#topology top_all22_sugar.inp
alias residue HIS HSE
alias atom ILE CD1 CD
alias residue HOH TIP3
alias atom HOH O OH2
alias residue OXY O2
alias residue CPS CT3
segment NAG {
first none
last none
pdb 3KLD_nag1.pdb
}
regenerate angles dihedrals
coordpdb 3KLD_nag1.pdb NAG
writepsf nag1.psf
guesscoord
writepdb nag1.pdb
ENDMOL
