Using RangeScan with randomize

multi131

Hi,

I'm trying to use the randomize functionality when doing a parameter RangeScan. I was able to get it to work, but I can't find information in the log file how to un-scramble the data to useful information out of it. I'm doing the following:

and from the log file I get the following information about that variable:
{'npoints': 11, 'randomize': 2, 'seed': None, 'start': 2.8, 'stop': 2.9, 'ty': 'RangeScan'}

How do I reassign the correct values to each run of the scan?

Thanks,
Malte

Hey Malte,

Unless you explicitly save the scannable as a dataset, you won't be able to recreate the exact sequence if it's randomized.

claytonho Unless you explicitly save the scannable as a dataset, you won't be able to recreate the exact sequence if it's randomized.

If you want to reproduce the sequences, just set the PRNG seed - this is not exposed in the GUI but should be easy to add or to do programatically. It is just this "seed" parameter which is set to None in the OP's example.

Otherwise, yes, the data from each point on the scan axis also needs to be saved as another dataset.
