Dear SPMers,
last week I asked to you about how acquisition variables can affect VBM
analysis. It seems that different acquisition protocols (i.e. different
TE, TR) can give different intensity values, and VBM doesn't be
performed correctly, since results can reflect different gray densities
or an artifact.
But, does it exist some possibility to modify gray intensities
posteriorly to the acquisition? Is there some matlab routine to modify
the images how it were acquired in another protocol?
Thank you very much in advance,
