Hi,
 I am trying to extract structures from the restart file that i have
obtained after equilibration (using SANDER)
The procedure that i have used is ( i am not sure whether right or wrong)

give the topology and restart files as inputs to ptraj and to output pdb
files

script used is ....

-------
ptraj topologyfile
trajin restartfile
trajout x.pdb pdb
go
-------

The AMBER ptraj program gets executed and it says that it has only one
frame to be visited, but actually i am supposed to have 50 in it. I am not
sure whether the procedure that i have used is right or wrong

can anyone please help me how to get all the structures.

Regards
