Hi Ying,

This is a frequently asked question.
You can find lot of answers in the AMBER archive.
You can also look at http://amber.scripps.edu/Questions/linmin.html

Good luck,

>Moreover,I found that this error was always come after "ncyc" finished. That is to say ,if I set "maxcyc = 6000, ncyc = 500,", this error will come after about 500 steps, if I set maxcyc = 6000,
>ncyc = 1000, this error will come after about 1000 steps.
