Hi John,
I assume all of the test cases passed in serial and parallel.
If you look closely at your calculation output you will see that the angle
I would suggest visually looking at your starting structure to see if you

My input file is
m8-minisation
&cntrl
imin=1, maxcyc =500,
ncyc = 250, ntb = 0, ntpr =1,
igb = 0, cut = 12,
/
The output file shows following lines

I had tried different value of cutoff and ntpr, but all gave the same
thanks in advance
