Preparing Data for Analysis
¥ Six preparatory steps are common:
H Image registration (realignment): program 3dvolreg
H Image smoothing: program 3dmerge
H Image masking: program 3dClipLevel or 3dAutomask
H Conversion to percentile: programs 3dTstat and 3dcalc
H Censoring out time points that are bad: program 3dToutcount or 3dTqual
H Catenating multiple imaging runs into 1 big dataset: program 3dTcat

¥ Not all steps are necessary or desirable in any given case
¥ In this first example, will only do registration, since the data obviously needs this correction
