[Insight-users] Re: randomness in MRIRegistration example

[Stephen R. Aylward]

Hi,

There is an appeal to leaving the setting of the random seed to the main 
app.  This way the user decides if a run/program should produce 
consistent results or not.   Also, this way the seed is not set multiple 
times.

Just a vote.
