Dear Nick, I have now used version 4.5.0 and the -randomness flag no longer gives errors, however, after 10 parallel runs of a subject with the -randomness flag set, I observe that the stats are completely identical. In the logs I can see that the line "setting seed for random number generator to 1234" is no longer there. In the earlier versions where the random initialisation was default I observed differences in the stats when I made the 10 parallel runs on the same subject as I have used this time - so it would seem that the random initialisation is not turned on when I use the flag. Can you please comment on this :)
Thanks, Pernille

Pernille,
My mistake, v4.4.0 still makes use of randomness. The next version, to be released in a couple weeks, with have -norandomness by default. The ReleaseNotes page has been updated.

Hi, In the release notes for version 4.4.0 it says that "The -randomness flag can be used to allow usage of a random seed", however, running the following command:
recon-all -all -nowmsa -randomness -subjid f4168_1r
gives the following error:
ERROR: Flag -randomness unrecognized.
Is there another way to reintroduce the randomness?
I am using the following version: v 1.133.2.51 2009/06/11
