Hi All,
Does anybody experience the following mystery? I am wondering if the problem was caused by amber7 or by our computer problem.
I did the same MD calculation (the same input file) twice. Output files were idential except timestamp. Both jobs were succesfully done according to the output files. All coordinates in their restart files generated last were identical. However, in some part of trajectories were different. To matter worse, output format were different, neither.
A trajectory file contains 670751 lines, however, another does 670257 lines. The former keeps the same output format in it, however, the latter does not like this (The first number in each line indicates the number of lines)

As you can see above, output format was suddenly changed and then suddenly recovered. All data above 99319 line and below 99433 line were identical with both trajectories.
I strongly hope someone gives me a clue to solve the mystery.
