Hey,
thanks for the quick reply. However, that was not exactly the point. E.g. in SPM, one can decide when writing the normalised images whether SPM should:
1.Preserve Concentrations: Spatially normalised images are not ”modulated”. The warped images
preserve the intensities of the original images.
OR
2.Preserve Total: Spatially normalised images are ”modulated” in order to preserve the total
amount of signal in the images. Areas that are expanded during warping are correspondingly
reduced in intensity.
I was wondering if there was a way to figure out whether FSL (FNIRT) preserves the concentrations of the intensity values during the normalisation process, or whether it's the other way round.
best, N.
