Hi Paul,

Thank you. Resample+refit works well, but the tracking results are bad for HARDI model.

You can see the full brain MINIP tracking results from the first attachment(Left: DTI model, right, HARDI model. Upper, all DWI volumes are used, lower, b>1500 volumes are excluded. Their tracking commands are listed. All these data are from the same subject.).

There are no structure connection between fmri rois either in HARDI model(the second column of the second attachment), though that can be found from DTI model.

So, how to improve the HARDI model results?

Besides that, when using all these volumes, the structure connection calced from different tracking model(the second picture is too width too show all tracking results, it need to be downloaded to see completely) for DTI model are more robust, though it REALLY took a long time.

Thank you,
