Hi Steve,
I'm sorry if I wasn't clear first time around. We want to use our gradient field maps to correct for distortion in the signal - and since we are also going to use melodic to clean up our data before running our first levels and groups analysis we were wondering at what point in the processing stream it is best to use the gradient field map - when we run the melodic, or after when we run the first levels on the denoised data? Or should it be used at both points?
Does that make any sense?!
