[MINC-users] minctracc and cropped images

[Simon Fristed Eskildsen]

Hi all,

I have a number of bitmap images. Each image is a coronal slice from a 
T1 MRI. Using rawtominc I have managed to create a minc volume from the 
bitmaps.
I have the original scan in dicom, which I have converted to minc using 
dcm2mnc.
Now I would like to align my volume created by rawtominc (let's call it 
"bitmap volume") with the original scan. However, the bitmap volume is 
cropped compared to the original scan, and minctracc does not seem to do 
a very good job aligning the two volumes. Is there a way to let 
minctracc know that the source does not have to match all of the target? 
Also, I don't need rotations in the transformation. Is there a way to 
force minctracc to not use rotations, only translations and scale?

Thanks,
Simon
