I am attempting to register two time series volumes using FLIRT.
I initially used avwmerge -t to combine my volumes (192KB each) into one
file. This gave me a .img of about 65MB. Following that I ran BET and got
a good extraction.
However after I run the registration (6 dof) on the file it returns three
files as expected but it has given me a .img that is only 192KB. Which is
equivalent to the size of one of the volumes previously merged together.
Is this normal or is there something I missed.
Thanks in advance for the help.
