I'm trying to run the DNA polyAT tutrial (amber 8) and I have amber 7 on irix
but sander is not runing the minimization in. First I got an error message about the input file, I changed the last line in the input file to end with &end statement instead of the /
Still sander is not runing but this time the error is different. This time the message said:
fmt: read unexpected character
apparent state: unit 8 named polyAT_vac.prmtop
last format: (12I6)
Unit 8 is a sequential formatted external file
*** Execution Terminated (115) ***

I do not now if there is format change between amber 7 and 8 in the prmtop file format and so I'm not able to solve the problem.
I'm a new user of amber so please any help will be appreciated.
