to coregister with an anatomical reference. you can probably read Dr. Mori's
answers in earlier threads if you keep the emails.</font></span></div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2">What i have done but didn't continue to use it, was to
reduce the size of the anatomical image to the size of the DT image using
diffeomap. Later did AIR in DTIstudio using the anatomy as a reference to the
Mosaic DTI images i had, which were cut in the same size as my anatomy. After
this coregistration there was a nice mixed image of anatomy with the
DTI. So then i saved this as separate analize file and proceeded to the DTI
analysis as usual. When it came time to draw my ROIs, I would open
the coregistered anatomy with DTI analize file, which know was exactly the
same position and size, and then i would have nice clear ROIs. The ROIs i would
draw either with ROI editor or DTIstudio.</font></span></div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2">I didn't continue to do this, because it is obviously
tedious method. So i proceeded to do all the DTI analysis in DTi studio, export
the files as Analize, and then coregister my anatomy images with another
program. It was hard for me to work with ROI editor because the resolution of my
DTI is relatively bad. So i had to use a different program. </font></span></div>

<div></div>I know DTI studio supports only intra-subject/intra-DTI
registration.<br>I tried to use Diffeomap, but it complained about images are
not of the same image parameters.<br>If you have a complete guide about how to
coregistration of DTI (e.g. 256x256) to High-resolution anatomy (e.g. 512x512),
could you share it with me and whole community?<br><br>I appreciate that in
