Hello John
Do you mean by this that reslicing at realignment (or just for realign &
unwarp?) are faulty prior to the recent updates and including spm5b? Or is
this just a matter of display? I'm perhaps being slow on the uptake here
but don't quite understand the description of the problem - would you mind
clarifying? Thank you!
And while I'm at it, thanks for for the new 'parallel' style GUI &
documentation :)
