Hi Damion,
Could you please send me just one subject fmri with its structural as well as the result you got? I will give a look to it but not just now because I am from Spain and here it is 05:30 am esrly in the morning. I will give a look into this in the next few hours.

Yes, I have a T1 image as well and am using it when running the flirt method. The biggest point of confusion is why my output image (that looks great and is definitely aligned to the atlas; verified by overlay in fslview) is just the single frame reference and not an entire 4d image like the input.Any ideas of what I'm overlooking? Or perhaps, if you have time, could you explain the workflow you'd use to accomplish this? From all I've read, I am doing it correctly, but my output says otherwise.DamionHi Damion, do you have structural T1 images for those subjects? A coregistration would be of great help when you have low resolution before MNI registration.
Kind regards,
Rosalia

This feels like a very basic question, but I can't seem to get it working the way I need. I apologize if this is a repeat post, but I was not able to find a solution that works for me.
What I am trying to do: I am trying to register a functional scan to the MNI atlas. I have successfully done this with flirt (turning off all smoothing, etc because I only want the transform step), but my output file is a single frame (reference file?). I have tried to do this with applyxfm as well, but the image gets moved around and at least one view ends up chopped off (I'm guessing because the voxel size of the acquired image isn't the same as the atlas?).
It's frustrating because this feels like it should be a rather simple function, but I can't seem to find anything about how to do this transform without running it through all the steps of FEAT. I'm hoping someone can point me in the right direction or to the proper tool (or perhaps knows what I'm doing wrong with FLIRT if that is, indeed, the correct tool to use).
Thanks in advance!
