Well, regardless of what option you select in the scanner, the gradients
outputted by DICOM to NIFTI conversion programs like MRIConvert or MRICron's
converter may vary from subject to subject if you have rotated the FOV. The
gradients applied by the scanner are the same; they are just corrected for
these rotations.
Peace,
Matt.

Hi,
Thanks for answer.
I was told that '... if all subjects use same protocal, the gradients sould
be
same. however,for Philips, if you select "Overplus" option during scanning
the
gradients will be changed dynamically accordin to the tilt-angles...'
The gradients I have might be in such cases.
Best!
Yuzheng
