Use the follwing statement after reading the molecular structure
file and the parameter file (parhcsdx.pro)
parameter
dihe (name ca and resid <??>) ( name C and resid <??> )
( name N and resid <??+1>) ( name CA and resid <??+1> ) 1250.0 2 180.0
end
Use the actual residue numbers for <??> and <??+1>
