(JHU-MNI-SS-T1), it gives me an error saying that the template needs to be a byte image. I thought this was supplied by the Diffeomorph software so would already be in the required format.

<b>Subject:</b> [Mristudio-users] How to recalculate gradient table of Philips DICOM files with 'gradient overplus' on</span></p>
<p class="MsoNormal"> </p>
<div>
<p class="MsoNormal"><span style="font-size:10.0pt; font-family:"Arial","sans-serif"">Hi: <br>
I have a dataset of DICOM files (a directory contains lots of .dcm files), and these data are collected from Philips device with "gradient overplus" option on. <br>
After googling, I found that the gradient table of these data should be recalculated if the "gradient overplus" option is on for Philips devices. And I found several tools: <br>
1 - DTI_gradient_table_creator <br>
</span><a href="http://godzilla.kennedykrieger.org/~jfarrell/software_web.htm#DTI_gradient_table_creator" target="_blank"><span style="font-size:10.0pt; font-family:"Arial","sans-serif"; color:#6611CC; border:none windowtext 1.0pt; padding:0in; text-decoration:none">http://godzilla.kennedykrieger.org/~jfarrell/software_web.htm#DTI_gradient_table_creator</span></a><span style="font-size:10.0pt; font-family:"Arial","sans-serif""> <br>
<br>
This tool can only parse data in PAR/REC format, however my data are thousands of separate .dcm files from a single patient.</span></p>
<div>
<p class="MsoNormal"><span style="font-size:10.0pt; font-family:"Arial","sans-serif""><br>
2 - DTI gradient table <br>
</span><a href="http://jp.mathworks.com/matlabcentral/fileexchange/41876-dti-gradient-table/content/dti_grad_table.m" target="_blank"><span style="font-size:10.0pt; font-family:"Arial","sans-serif"; color:#6611CC; border:none windowtext 1.0pt; padding:0in; text-decoration:none">http://jp.mathworks.com/matlabcentral/fileexchange/41876-dti-gradient-table/content/dti_grad_table.m</span></a><span style="font-size:10.0pt; font-family:"Arial","sans-serif""> <br>
<br>
It only works for a multi-frame dcm file. <br>
<br>
My questions is: <br>
a - How can i recalculate the gradient table from these .dcm files ? <br>
b - Is there any other tools suited for this situation ? <br>
<br>
Thanks </span></p>
