Dear namd users !

I have tried calculating the
interaction energy between the lipid bilayer and
a peptide. ( peptide inside a lipid bilayer )

when i used the namdenergy.tcl

and gave the following in the tkconsole of vmd after loading all the needed
files
set sel1 [atomselect top "protein"]
set sel2 [atomselect top "lipid"]

namdenergy -dihe|-nonb -sel $sel1 -self 2 -ofile "respro.dat"

it gave the error

------------- Processor 0 Exiting: Called CmiAbort ------------
Reason: FATAL ERROR: CAN'T FIND CROSSTERM PARAMETERS FOR C NH1 CT2
C NH1 CT2 C NH1

Charm++ fatal error:
FATAL ERROR: CAN'T FIND CROSSTERM PARAMETERS FOR C NH1 CT2 C NH1
CT2 C NH1

how to solve this

thanks in advance

regards
balaji
