Hello,
Has anyone tried using sigloss with interleaved slice collection? So far I
have calculated the sigloss image, and used the flirt options --inweight
(sigloss output), -searchcost (normcorr) and -cost (normcorr) to register
the fmri image to our PD image. These options are successfully moving the
alignment in the right direction by about 1 mm, but there is still about 4mm
to go. I have tried registering to the T1 as well, but it seems to move the
alignment in the opposite direction! Does anyone know if interleaved slice
collection disrupts the sigloss calculation or have any suggestions? Thanks.
Chris Bell
PS: Any suggestions on how to best apply ventricle weighting from the fmri
to a PD or a T1, to achieve better alignment.
