<p class=MsoNormal style='margin-bottom:12.0pt'>When you load the REC file
using "Mri3DView", make sure how many images are in the file. For
example, if you used Philips "High" table, you have 1 b0 + 32 DWI + 1
extra image, total 34 images. The last one is an isotropically-weighted image
generated from the DWIs. Then make sure your gradient table. Most likely, the
number of images in your REC and the gradient table are not matching.<br>
<br>
For example, you may have only 33 lines in the table. For the final image,
which you don't use, you can add an extra line with 33: 100, 100, 100. The
first "33" is the line number (34th table row), and "100, 100,
100" sends a message to DtiStudio "don't use this image".<br>

<p class=MsoNormal>>Dear all<br>
I have a completely basic question<br>
when I try to load Philips Rec images in DTI studio I can do it, however the
same set file (which is a DTI ss-EPI sequence )gives the following error
when I try to do DTI mapping :<br>
the file is Bigger (and sometimes it says smaller)than a DWI sequence!<br>
where is the problem?<br>
regards<br>
