fod2fixel error said: Cannot use image template_mask.mif as mask image; dimensions do not match FOD image

Hi experts,

When I trying to do fixelbased analysis, I encounter one error.

The command is : fod2fixel -mask /scratch/sftaylor_armis/Shared/OCD_DTI/fixelbased/OCDPre_vs_HcPre/template/template_mask.mif fod_in_template_space_NOT_REORIENTED.mif fixel_in_template_space_NOT_REORIENTED -afd fd.mif

The error said: fod2fixel: [ERROR] Cannot use image “/scratch/sftaylor_armis/Shared/OCD_DTI/fixelbased/OCDPre_vs_HcPre/template/template_mask.mif” as mask image; dimensions do not match FOD image

When I try to check the dimension of template and fod image using mrinfo
the dimension of template_mask.mif is
Dimensions: 136 x 170 x 133
image

The dimension of fod_in_template_space_NOT_REORIENTED.mif:
Dimensions: 136 x 170 x 133 x 45

Is there any wrong about this?
Thank you so much.

Best,
Huan
