I thought it would be good if I attach required files here.
As we can see in log.min file minimizer's working finely, even if I do not
Is it that it takes 100 as ftol, where 100 is my maxiter?
Can anyone solve the puzzle?
you have to very carefully check which version you are using.
in newer patchlevels (since mid-april 2008, IIRC) the minimize
command needs four arguments. before it was 3 arguments. the
new argument was inserted at the beginning. now you can set
force and energy tolerance before there was only one tolerance.
ps.: the dihedral code you posted is not compatible with
the current release. it still uses the old interface to
compute the virial...
