<h1 style="font-weight: normal;" class="YfMhcb"><font size="2"><span id=":11f" class="VrHWId">I find Hangyi said that </span></font>"DTI Mapping" does not accept Analyze DWIs, for NRRD, the header should
follow the NRRD-DWMRI format, not the NRRD format, they are not same.
for RAW format, it is supposed that each file contains only one image

volume
,that is, b0+15 direction means 16 raw data files in the same directory. Then I click "DTI Mapping", check "Raw files", the error bar hints <font color="#ff6666">"File size is less than expected:ImgWidth*ImgHeigth*2bytes+header... " </font><br>
Is there anything wrong?<br><br><div class="gmail_quote">On Tue, Dec 16, 2008 at 10:21 AM, 李猛 <span dir="ltr"><<a href="mailto:albertleemon@gmail.com" target="_blank">albertleemon@gmail.com</a>></span> wrote:<br>

<div>Dear all<br>
<br>
<br>
Hi.<br>
<br>
If I use the AIR module to do eddy correction, It always crashes! So I<br>
turn<br>
to FlAIR module in FSL. If It means I can't use DTIStudio anymore in the<br>
follow-up produces?Is there any method to load NIfTi data in DTI Mapping<br>
module?<br>
<br>
Which software can convert the NIfTi data into Raw or NRRD<br>
format?Please<br>
let me know..<br>
<br>
Thanks a lot!<br>
<br>
<br>
