Basically, you'll have to do your second question in order to
accomplish the first using Route, Switch, and Inquire modules.

I have a script executing mostly fine. It displays data as a time series of
frames, user selectable as glyphs or isosurfaces. The data is filtered through
include to allow user selectable ranges. This works until for a given frame,
there is NO data from include to colormap (because all the data is outside the
selected range)
In this case I get an error msg from colormap becuase there is no data. My
fistr question therefore:
Is there a way of getting DX to ignore such errors during execution, rather
than stop throw up the msg & visual editor windows (I'm running from the GUI)?
The second question, providing more flexibility:
Can I interrogate the data output from include to allow flow control (to not
carry on through that portion of the script if the data count is zero? (& if
so, how do I go about it?)
(Basically, how do I implement the following structure in DX:
COUNT=`get_count`
if [ $COUNT -eq 0 ] ; then
break
fi
Thanks,
Brent
