Shiyu,

 

If you have access to a copy of the original (unmoved) structural image, you can determine the reorientation you manually applied based on the two transformation matrixes in the original and moved structural image, and then apply that same transformation to your functional images. I wrote a small function to do this (attached) some time ago, which I haven’t tested extensively, so I can’t guarantee that it works all the time.

Hi David,

I reorient and set the centre of the structural images based on the template for all cases. But then I realized I should do the reorientation for functional images at the same time so that I can coregister the functional image to structural image in preprocessing. I forgot the value of the radians I used for structural image. I did it all manually and the value varies between cases. Where can I find the value. And if I can find them, where should I put them down to reorient my functional images?

Hi Shiyu,

 

If by reorient you mean to apply some degree of rotation, you can quickly use the “Display” section, apply the desired rotation (remember is in radians) and then apply those parameters to as many images as you select.

 

Regards,

Hello everyone,

Sorry to bother. But I made a mistake when manually reorienting the images. I was trying to make a study specific structural template. So I forgot to reorient the functional image together with the structural image. Is there any way that I can do the same reorientation to functional image for each case later? This may be a improper question here. But I searched online and didn't find any solution. Do I have to redo the reorientation for all the cases?

Thanks!!

Shiyu
