Thanks, that would solve the problem I was having.

Please feel free to end this conversation here, but if you can spare the time I’d be very interested in an example of a multiple split run for my own education/understanding/curiosity? I assume you mean processing subsets of the input, but can’t see how to do that (after experimenting on the command line and searching the documentation) except —number=l/k/n which does know the size of the total set?

Thanks again, Ben
