RE: AMBER: mdcrd file

Dear Jianhui,

You can do this with ptraj:

trajin mdcrd start stop offset
trajout mdcrd_new

Where start is the first frame of mdcrd you want (e.g. 1) and stop is the
last frame you want. And offset is the frame step you want. E.g. 2 would
give you every other frame.

Note you can also load partial mdcrd files into vmd.

In the molecule file browser you can select a start a stop and a stride
value.

All the best
Ross
