Subject: question on ouput of sander

Dear All,

I have a question about my output.
The input shows below.
But I can get all the ouput files but the -x sa.crd and -e sa.en.
Any suggestion?

By the way, I get an error from the mdinfo file
 Ewald error estimate: 0.1000E+01
What do this mean?

Thank you in advance.
