0 - read dx/dy values for registration; OUT is treated as IN file/rec
1 - generate dx/dy/dz plots for each time point
2 - generate dx/dy/di plots for each slice separately
4 - censor images where dx or dy is greater than MAXPCT
010 - print volume motion parameters
020 - print image motion parameters
040 - motion censor data by volume (default is by image)
0100 - report global X/Y motion values (mean, stdev, max)
0200 - use the most frequent position as reference (otherwise use mean value)
0400 - do statistics
01000 - create a point ROI at the image center-of-mass for the central timepoint
04000 - censor MAXPCT is maximum fraction of all images to censor
3 - generate all plots (default)
