We have some functions to mutate the reg, even more in BatchExperiments. But again, yes. \r\n\r\n> If there is some modification to all the results that is desired, one\r\n> could use batchMapResults to transform and populate a new registry.\r\n\r\nYes. That was the idea. \r\n\r\n> However for\r\n> a really large result set it might be desirable to do this in place. Clearly there is some\r\n> risk of corruption of a useful result set. Has this been considered? Any major conceptual\r\n> problems?\r\n\r\nIn place means: Exchange the current results r_i by f(r_i)  in the current reg dir? \r\nIn parallel maybe? So this is like batchMapResults, what is simply different is where the results are stored?\r\n\r\n"}}
