Preparing fMRI Data for Statistical Analysis
John Ashburner · Neuromethods · 2009
This chapter describes the procedures applied to fMRI data prior to their statistical analysis. This usually begins with converting the data from original MR format to a form that can be used by the analysis software. The data are then motion corrected. If an anatomical scan is collected for the subject, then it would be co-registered with the fMRI, and may serve to estimate the warps needed to spatially normalise the fMRI to some standard space. The final pre-processing step is usually to smooth the data.
