you can use ptraj to do this. lots of ptraj examples are in the Amber
tutorials,
the specific syntax for the dihedral command is page 251 of the Amber 9
manual.
your script might look something like:
#!/bin/csh
ptraj prmtop << EOF
trajin md.x
dihedral phi2 :1_at_C :2_at_N :2_at_CA :2_at_C out PHI2.data
go
EOF
