[Chimera-users] Can I use wait command over Rest service?

[Mungo Carstairs (Staff)]

Hi Elaine,

Thanks. I tried as separate commands and now at least I can see the effect, but only as a fast flicker regardless of the wait value (or no wait command).
It does seem that wait is ignored over Rest. I guess I could code the wait at my end but that would be a last resort.

Concatenating the commands on the command line does give the wait behaviour I am hoping for (so somewhat contradicts the link you passed in that the display is redrawn a couple of times).

Sleep works, but is too slow for my purposes (minimum one second delay), which include tracking over a sequence with the mouse at some speed.

Hi Mungo,
If I understand correctly, stringing the commands together with semicolons means to only show the result at the end.

“...display is not redrawn until the last command in a semicolon-separated series has been executed.”
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/usageconventions.html>

 I’d expect it to behave more like you want as two separate commands:

display #0:30.A;wait 20
~display #0:30.A

… although perhaps that is more trouble to script.  If this is just for “live” execution (not recording as a movie) the “sleep” command may be an alternative to “wait,” although it may also require using two separate commands.

I hope this helps,
Elaine
