<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am relatively new to DTI studio and have been using
successfully to do tractography on infant brain data collected on a Seimens. I
am now trying to analyze child brain data collected on a Philips. I can get a
clear image, but as soon as I try a tensor calculation, the image quality
degrades significantly (no matter what the background noise level I set it to).
I made gradient tables from the PAR file (forwards and backwards) and also
flipped the z as the tutorial suggests. Any suggestions on how I can solve this
problem?<o:p></o:p></span></font></p>
