I have to use the New Segment function of spm, but the seg8.mat file produced cannot be used in the deformation module, and I cannot use the deformation field as I want to apply the deformation to fMRI and do not want to resample it to T1 resolution. I thought about reslicing the deformation field but it contains the 3 images so that processing is not that easy in SPM, especially because I would like to be able to use batch processing.
It seems that the seg8.mat contains enough information to apply deformation but I cannot find how to do so. Is it possible to create a mock seg_sn.mat from the seg8.mat by adding the VG and VF with convenient mat and dim field and does the Twarp in seg8.mat is equivalent to the Tr in sn.mat.
I think I am not the only one struggling with this.
Thanks, if anybody could help I would be grateful.
