Hi, admistrator
first, above all, thank you for providing your program
Our researchers have studied ADHD adolescent and their brain activity used in fMRI.
Our study is block design and I have analysed this by using SPM8.
lately, I informed DPARSF program. It's very comvenient and brilliant tool.
But I don't know whether I should change the voxel size 3 3 3 which is already determined in DPARSF program to 2 2 2 which is determined in SPM 8 or not. ( In SPM 8, default voxel size is fixed (determined) 2 2 2 .)
Should I leave the voxel size 3 3 3 in DPARSF even though the voxel size of fMRI set point which we used is 3.8 3.8 4 ?
Should I change the determined voxel size 3 3 3 to 2 2 2 which is default voxel size in SPM 8?
or Should I change the determined voxel size 3 3 3 to 3.8 3.8 4 which is the voxel size of our fMRI set point?
I ask to be excused my poor ability in english, thank you. Have a nice day

Hi,
You can use 2 2 2.
However, as your original voxel size is 3.8 3.8 4, reslicing to 2 2 2 can help you to acquire more information, but occupy more disc space instead.
Best,
