Hi Gabriel,

I'm not sure I know what you mean. I think we use flirt to compute the motion parameters, then we just average the images in the aligned space (which I think is to the first scan specified, but Doug would know)

cheers

Thank you Bruce for you answer, but i still have the doubt, is motion 
correction from the FSL the method to average the images? or is another 
method... I wrote motion correction cuz in the -help of recon-all says that 
theyr made in the same step, but not to be the same process. but whatever is 
not explain which is the averaging method, even when i look in the  FS page, it 
appears the mri_average, but has no methodology explained.

Best
Gabriel
