modulation in dparsfa2.3

Submitted by fish on

Dear Dr. Yan,

Could I ask that in your DPARSFA2.3, if I only used T1 image for segment and normalize bu using T1 image unified segmentation, the result of mwc1 image, I mean modulation files, is it m or m0( non-linear only)?

Any advice will be appreciated.

Best

Hi Fish,

In SPM12, "the warped data are not scaled by the Jacobian determinants when generating the "modulated" data. Instead, the original voxels are projected into their new location in the warped images." -- Page 46, SPM Manual.

DPARSF calls SPM functions, thus has the exact procedures as SPM.
