Hello,
We have problems with aligning single-slice data which consist of R2-maps
from a visual study. Our flirt-version is 4.0. Since the data is parameter
maps, we wouldn't like to touch the pixel intensities. Intensities were set
to range of 100...1100.
Mcflirt gave us an error:

Basically the same error was produced when we tried modified stack of
NxMx3xseries (same slice three times as third dimension) instead of
NxMx1xseries.
We also tried to use previously mentioned schedule files (3dof) for
alignment, but we got only background intensities as a result. High
resolution image is available from the same slice.
Any ideas?
Help appreciated,
