关于文章中 Jacobian of the nonlinear warp field in order to compensate的问题

 
各位老师：
今天看到一篇文献中有做这个,因为对fsl不是太熟，所以想问下spm能不能完成以下操作：

The resultant GM images were registered to the ICBM152 GM template (included with FSL) with 2×2×2 mm3 resolution, using a nonlinear registration (FNIRT). These images were then averaged together with their mirror images, in order to create a symmetric study-specific GM template. Each individual’s native GM image was then registered to this studyspecific GM template using FNIRT nonlinear registration, and each voxel was subsequently divided by the Jacobian of the nonlinear warp field in order to compensate (“modulate”) for contraction or enlargement caused by the non-linear transformation. The modulated normalized GM images were then smoothed with an isotropic Gaussian kernel with a sigma of 3mm (analogous to a 7 mm FWHM).

除了这一步：别的我还比较确定可以用spm实现： and each voxel was subsequently divided by the Jacobian of the nonlinear warp field in order to compensate (“modulate”) for contraction or enlargement caused by the non-linear transformation. 请问这一步能用spm实现吗？具体到哪一个步骤呢？

谢谢

祝好
