Can the voxel size of the 5ttseg.mif file generated from the T1 structural image(1mm) be different from that of the align.mif(2mm) diffusion image file?

Can the voxel size of the 5ttseg.mif file generated from the T1 structural image(1mm) be different from that of the align.mif(2mm) diffusion image file?

code:

dwi2response msmt_5tt align.mif 5ttseg.mif ms_5tt_wm.txt ms_5tt_gm.txt ms_5tt_csf.txt -voxels ms_5tt_voxels.mif

Hey Qianjinbo,

I’m not quite sure what you mean (maybe I’m just interpreting your question wrong). The 5tt segmentation happens in T1 space and accordingly will have the same voxel size as your T1. I assume your T1 is a different resolution than your DWI, so the segmentation and DWI will have different voxel sizes.

Best,
