Of course, I should have checked the FAQ first!!!
Well, I did as suggested and now the brains are within the FOV. Unfortunately, they are still not
overlapping very well.
I have two func brains that were successfully registered to standard. I then applied func2standard
standard FOV=[182 218 182]
func FOV=[200 200 93.5]
diff = (func FOV - standard FOV)/2
= [9 -9 -44.25]
To adjust for FOV, I added diff to the x,y,z values of the two func2standard.mats. While they were
mostly overlapping, they were off by up to 25 mm.
Should I just register all the funcs to one func? Then there wouldn't be any FOV issues.
