[Insight-users] statistics on two groups of image volumes

[Dennis Jen]

Hi Luis,
  I'd like an arbitrary number of image volumes ideally, and I imagine 
between 10-100 volumes as input.  The images will be registered and the 
same size.  My ultimate goal is to write a statistics filter that would 
be applied to the homologous pixel across two groups of image volumes, 
so the two collections of image volumes would be input.  I was hoping 
that visiting homologous pixels across a group of image volumes and 
applying some sort of strategy might already be encapsulated within a 
filter.
  Please let me know if I can provide more details.
  Thanks,
    Dennis
