Hi,
adding a 'refresh' (http://www.pymolwiki.org/index.php/Refresh) seems to
work:
```
from pymol import cmd
cmd.fetch('1nmr', async=0)
for i in range(1, cmd.count_states()+1):
cmd.set("state", i)
cmd.png("%d.png" % (i), width=1000, height=1000, dpi=300)
cmd.refresh()
```
On
Hi Dd H -
`cmd.set` is the wrong command to use here. (It's for changing settings, not
for going through states, although some settings can be applied to only a
specific state).
Instead, you should use `cmd.frame(i)` to move to that frame (state) number.
Note that the `width` and `height`
