[Mristudio-users] image coregistration

[Youngbin Kwak]

Hello all,

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.

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?

Another question I have is, when I perform AIR registration for all the dwi
images, there are new files created labled AIR_filename.
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?
Or should I get rid of the original guys from the image tab and only have
the new files available before performing tensor calculation?

thanks a bunch!
