Dear Philippe,
there's an example of the sampler in the manual
In order to do scans, it's best you set RASTER=TRUE in the SAMPLE command, especially if you want to do multi-dimensional scans. Fuhrtermore, make sure you do not have any RANDOM=TRUE in the
individual SAMPLING commands. The sampler has the possibility to evaluate objectives like the optimizer.
http://amas.web.psi.ch/opal/Documentation/master/OPAL_Manual.html#sec.optimiser.opt-pilot-commands
The sampler then writes the objective output to the JSON file.
I've never used this option, hence, I do not have an example at hand. But maybe somebody else has one.
When you defined the objectives (i.e. obj1, obj2, ...), you have to put them into a list OBJECTIVES = {obj1, obj2, ...} in the SAMPLE command.
I hope this helps.
Best,
Matthias
