Use the follwing statement after reading the molecular structure
file and the parameter file (parhcsdx.pro)


dihe (name ca and resid  <??>) ( name C and resid <??> )
     ( name N and resid <??+1>) ( name CA and resid <??+1> )  1250.0      2 180.0

Use the actual residue numbers for <??> and <??+1>
