Dear Jim, Bill and Chuck:
Thank you all very much for your prompt reply and suggestions.
This " Floating Invalid" appeared when I run sander MD. Then I tried to run Min first for some steps and then I continue to run MD. This problem disappeared. Now everything is fine though I still don't not why so.
Thank you once more for your kind help.
Regards, Lifang Xu
