Hello (Glen?)

In trying to convert a dataset from TTA to MNI, it seems that the option -newgrid does not actually change the voxel size of the output dataset (with respect to the input dataset), using the command

3dWarp -tta2mni -newgrid 2 -prefix data_mni data_tta+tlrc

Is there any special caveat to the usage of the option that I am not aware of?

thanks for any comments!
