I am a newbie in fMRI. We have just activated the fMRI
functionality on our Siemens Avanto 1.5T machine and have carried out our
very first finger tapping experiment! The structural image data size is
256x256x176 with pixel dimension of [0.9766 0.9766 1] and the functional
64x64x34 with pixel dimension of [3 3 3.75]. The segmentation
process on SPM8b takes longer than I can bear waiting for it to complete! I
have waited for an hour of going over 1500 iterations with no convergence
in sight! Am I doing something silly? Any help on this would be
really appreciated.
