Dear rick,
I think i'd better reexplain my question:
when i check the output from the following command, i found that the grid spacing specified by dxyz option make no difference on the grid of the input, which is also shown below. What's the effect of this command and where's the corresponding information?
adwarp -resam Cu -dxyz 3 -apar 10-anat-ns_shft_alBOLDEC_shft+tlrc \
-dpar 10-BOLD-EC-volreg-lp-dt_temp_shft+orig
10-anat-ns_shft_alBOLDEC_shft+tlrc: voxel size=2x2x2, grid=91x109x91
10-BOLD-EC-volreg-lp-dt_temp_shft+orig: voxel size=3.312x3.312x3.312, grid=64x64x48
10-BOLD-EC-volreg-lp-dt_temp_shft+tlrc: voxel size=3.312x3.312x3.312, grid=64x64x48
Best,
Peng
