Hi Dr. Dan,
Thanks very much for your reply. The version of AmberTools is 1.2, and of course I have applied all the bugfixes. The attached files are input and output files for the analysis. And I also checked the output file, but there was not any error. Hoping that you can figure it out. Thank you again.
