Hi all,
I would like to use FSL to perform a rigid body registration between two different modality scans. The following commands register the two images,
```
flirt -v -in to_transform.nii.gz -ref ref_image.nii.gz -out transformed_image.nii.gz -omat transform.mat
flirt -v -in to_transform.nii.gz -ref ref_image.nii.gz -out transformed_image.nii.gz -omat transform.mat -init -applyxfm transform.mat
```
However, I do not want to reslice the transformed image into the reference image space, as the input image has a much higher resolution than the reference image. Is there a way to do this using FLIRT/FLS?
Thanks in advance!
Cheers,
Aaron Capon
