Afni3dTstat

Afni3dTstat is a wrapper for the AFNI (RW Cox, NIH) 3dTstat application.
Computes one or more voxel-wise statistics for a 3D+time dataset and stores them in a bucket dataset.
The AFNI 3dTstat program was written by B. Douglas Ward, Medical College of Wisconsin.
For more information about the AFNI package, see the AFNI Homepage

Information to be entered

• Input dataset
  Restrict files to AFNI 3D+time datasets only. The input dataset may use a sub-brick selection list, as in program 3dcalc.
• Prefix
  Specify the prefix of the output bucket dataset [DEFAULT = 'stat']
• Type
  Type of storage of the output: 'byte', 'short', or 'float' [DEFAULT=float]
• mean
  Mean of input voxels [DEFAULT]
• slope
  Mean slope of input voxels vs. time
• stdev
  Standard deviation of input voxels
• stdevNOD
  Standard deviation of input voxels [UNDETRENED]
• cvar
  Coefficient of variation of input voxels = stdev/fabs(mean)
• cvarNOD
  Coefficient of variation [UNDETRENDED]
• MAD
  Median absolute deviation of input voxels = median(|voxel-median(voxel)|) [UNDETRENDED]
• Durbin-Watson
  Durbin-Watson Statistic of input voxels
• min
  Minimum of input voxels [UNDETRENDED]
• max
  Maximum of input voxels [UNDETRENDED]
• median
  Median of input voxels [UNDETRENDED]

• Menubar
• Toolbar
• Output window
