Hi all,<br><br>Please try the following. I think Siemens changed their 12-orientation scheme some time ago and this should work for VB13 and also VB15, I believe.<br><br>0: 0, 0, 0<br>1: 1.000000, 0.414250, -0.414250 <br>

Hi Bruce,Thanks for your gradient table. I can't get this to load the data. Iget the error message "forgot gradient table" which may be becausethere are only 12 lines, instead of 13 (0 to 12), so when I number thelines provided, I get a different error message "forget gradient ofB0-image?"<br>
How do you use this gradient table?<br>
Thanks,Kevin<br>
