Hello Camino Experts, <div><br></div><div>I encountered a problem when I followed the scripts in the tutorial of the Q-ball in 'Multi-fibre/HARDI Reconstruction'. I used the example human data provided in the tutorial. Things went well until I ran sfplot. I got a number of messages complaining that the backdrop image was smaller than expected: </div>
<div><br></div><div>Aug 8, 2012 4:48:06 PM apps.SphFuncBitMap readBackDrop</div><div>WARNING: Backdrop image smaller than expected. Continuing...</div><div>Aug 8, 2012 4:48:06 PM misc.LoggedException logException</div><div>

<div><br></div><div>At the end I still got the output file dwi_ODFs_slicear.rgb with size about 38.5M. The ODF image can be displayed but there is no background image. </div><div><br></div><div>I was wondering what could be the problem of the backdrop image in sfplot. I followed every step in the tutorial except that I had to change byte length to 4 in running 'split' for fa.img because its data type is float, i.e.</div>
<div><div><span class="Apple-style-span" style="color:rgb(80,80,80);font-family:monospace;font-size:11px">split -b $((112*112*4)) fa.img splitBrain/fa_slice ,</span> </div></div><div>so that the resulted slice number was matched to the original fa.img (the backdrop image). The problem was the same in both Linux and Mac.</div>
<div><br></div><div>Furthermore, is there a way to display ODF in 3 different views (axial, coronal, and sagittal)? </div><div><br></div><div>Thanks in advance for your suggestions. </div><div><br></div><div>Zhuang</div><div>
