<div>Hello all,</div>
<div> </div>
<div>I'm trying to create an ROI for performing tractography. What I'm planning on is to create an ROI that is defined in a normalized template and then convert it to native space. In order to do this, I'd first like to coregister a high-resolution anatomical image to the b0 image, so that however I create ROI on the anatomy file would parallel the location of DTI images.</div>
<div> </div>
<div>In order to do this, I've loaded the anatomical image and selected mutual-Info image registration option. I chose b0 image as reference and the anatomical image as image to be registered and used rigid body transformation. However there was an error message saying "RegImgFile.tmp was not found". Can someone help me out resolve this issue?</div>
<div> </div>
<div>Another question I have is, when I perform AIR registration for all the dwi images, there are new files created labled AIR_filename.</div>
<div>Does the program know that it should use the newly created files (i.e. AIR_filename) to perform tensor calculation and the rest of the step?</div>
<div>Or should I get rid of the original guys from the image tab and only have the new files available before performing tensor calculation?</div>
<div> </div>
<div>thanks a bunch!</div>
