Dear SPMers, I?have a simple question about the interpretation of the realignment parameters saved in rp_*.txt file when using the "Realign:Estimate & Reslice" SPM function . The rp_*.txt file contains just a list of 12 numbers (e.g. 1.0103030e-014 1.2101431e-014 0.0000000e+000 0.0000000e+000 -2.1734570e-051 -1.5616324e-016 -1.5004945e+001 2.6234784e+001 2.6747571e+001 -1.1082900e-001 -3.3493469e-002 -4.0569124e-002) but I?m not sure about how should I read them in order to build the related transformation matrix. Best regards, Antonietta
