Sorry for my slow reply.<br><br>Here are the old and new Siemens 12. You can try both. If you use a wrong one, the color map doesn't make any sense. So you can find which is the correct one for you.<br><br>Also, Siemens users have to click "rotate if applicable" check box beneath the gradient table input section, if you are using oblique-angle imaging. This automatically read the oblique angle information and rotates the gradient table.<br>
<br>You may also check the new button next of the gradient table input section that can extract gradient information from Mosaic file. So no need to specify the table and rotate it. This works for VB15 operating system.<br>

Hi Hua,<br><br>We usually do not extract gradient info from any header information because there are many issues related to the gradient table and it is difficult for us to keep track of all different formats especially when the raw MRI data went through other software programs. The only exception is Siemens DICOM after VB15, which is supported by DtiStudio for automated gradient table extraction.<br>
<br>If you tell us the type of scanner you used and operating system, we may be able to provide a table.<br><br>Susumu<br><br><div class="gmail_quote"><div><div></div><div>On Tue, May 18, 2010 at 6:42 PM, Hua Zhang <span dir="ltr"><<a href="mailto:hzhang84@asu.edu" target="_blank">hzhang84@asu.edu</a>></span> wrote:<br>
