Dear all

Here is my input file

 minimize system
 &cntrl
   imin=1, irest=0, maxcyc=30000, ncyc=50,
   cut=9.0,
   ntb=0, ntpr = 100, ntr=1
 /
group input for cart restraints
100.0
RES 32 514
END
END

The process failed at 18100 step. Last time I did another work, and I
adjusted maxcyc and ncyc, the work went through.

Here, I have a question. Is there any relationship between maxcyc and ncyc
setting? I can set randomly or I can follow some rules.

Thanks

Jason
