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)
