fScan Reference Manual, Chapter 2 (CmdLineOptions): stability
Stability -- Calculate displacements of center-of-mass
usage: -stability flag outname refimg slice maxpct levelmm levelpct1 levelpct2
FLAG - can take on the following values:
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)
REFIMG - reference time point for image registration (default=0)
SLICE - If specified, only that slice is done, otherwise all.
MAXPCT - Used when motion censoring (FLAG & 4). Images with displacement greater than MAXPCT of a voxel will be omitted from further analysis (default MAXPCT = 50% for images, 30% if censoring volumes(flag 32)). If FLAG 0400 set, displacement minimum is default (50% img/30% vol) but that threshold is increased if necessary such that no more than MAXPCT of all images are censored.
LEVELMM - minimum motion level for reporting percent of images moved (default: 1 mm)
LEVELPCT1 - (default: 5)
LEVELPCT2 - (default: 20)
