<div>Hello DTI Experts,</div><div><br></div><div>I am trying to do an atlas based analysis using LDDMM. My goal is to do an anlysis on my FA/MD map such as done in <a href="http://www.ncbi.nlm.nih.gov/pubmed?term=20570617">http://www.ncbi.nlm.nih.gov/pubmed?term=20570617</a> (paper by Zhang). Therefore, I have used the steps described in <a href="https://www.mristudio.org/wiki/user_manual/diffeomap">https://www.mristudio.org/wiki/user_manual/diffeomap</a>.</div>
<div><br></div><div>I first processed the DTI data using 'DTI-Studio' and then skull stripped. To obtain the AIR and LDDMM transformation matrices I co-registered my skull stripped FA/MD/B0 map with 'JHU_MNI_SS_b0_ss' template using AIR and then used 'FA + b0 dual-contrast LDDMM' with 'JHU_MNI_SS_b0_ss' and 'JHU_MNI_SS_FA_ss' templates. </div>
<div><br></div><div>After obtaining the LDDMM matrix, I apply the Hmap to the 'JHU_MNI_SS_WMPM_TypeII' template. But it looks to me the image I got is having some problem. I am not sure if doing some mistakes. I used trilinear interpolation for Hmap.</div>
<div><br></div><div>Can anyone please tell me if I am following the correct procedure? Where I may go wrong?</div><div><br></div><div>Thanks in advance,</div><div>Manoj</div>
