[Mristudio-users] problems with tensor calc

[Zwicker, Jill]

Hi DTI Studio users,
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?
Thanks for your help.
