size of the disaggregation matrix

[Anne Hulsey]

Hello,

I am using disaggregation for New Zealand sites, using the NSHM source model and a maximum distance of 400km. When I use 10km bins, I get an error: ValueError: The disaggregation matrix is too large (2488320 elements): fix the binning!

20km bins corrects the error but I would like to use 10km and still keep the underlying hazard calculation at max=400km. Is it possible to use a custom set of bins, e.g. 10km bins up to 100km and then 50km bins?

Thanks,

Anne

It is not possible, however you can implement the functionality yourself, the relevant line of code is https://github.com/gem/oq-engine/blob/master/openquake/hazardlib/calc/disagg.py#L78

That's a good idea--thanks for pointing me to the relevant line.
