Synopsis: ifird(''integer'') = ''integer''<br />
<br />
Number of the first dihedral angle belonging to the residue n.<br />
<br />
The function returns the original index of the first (rotatable or<br />
fixed) dihedral angle that belongs to the residue with the given index,<br />
or the special value ifird(nr+1) = nd+1.<br />
<br />
This function is useful, for instance, to construct a loop over all<br />
atoms of a given residue, i:<br />
<br />
do j ifird(i) ifird(i+1)-1<br />
print "Angle $dnam(idord(j)) of residue $rnam(i) $rnum(i)"<br />
end do</div>Admin
