NAME
interleaved_bad_slices - Find bad slices in a time series of interleaved images (e.g., a resting-state fMRI series).
SYNOPSIS
interleaved_bad_slices ImagePaths
DESCRIPTION
This tool reads a time series of 3D images and detects outliers.
OPTIONS
Global Toolkit Options (these are shared by all CMTK tools)
- --help
-
Write list of basic command line options to standard output.
- --help-all
-
Write complete list of basic and advanced command line options to standard output.
- --wiki
-
Write list of command line options to standard output in MediaWiki markup.
- --man
-
Write man page source in 'nroff' markup to standard output.
- --version
-
Write toolkit version to standard output.
- --echo
-
Write the current command line to standard output.
- --verbose-level <integer>
-
Set verbosity level.
- --verbose, -v
-
Increment verbosity level by 1 (deprecated; supported for backward compatibility).
- --threads <integer>
-
Set maximum number of parallel threads (for POSIX threads and OpenMP).
Input Options
- --slice-orientation
-
Define slice orientation of the diffusion images. Supported values: "axial", "sagittal", "coronal", "slice-x", "slice-y", "slice-z", where the default is "axial", or use one of the following:
- --axial
-
Axial slices [This is the default]
- --sagittal
-
Sagittal slices
- --coronal
-
Coronal slices
- --slice-x
-
X coordinate axis is slice direction
- --slice-y
-
Y coordinate axis is slice direction
- --slice-z
-
Z coordinate axis is slice direction [This is the default]
Bad Slice Detection
- --metric
-
Image-to-image similarity metric to compare neighbouring slices. Supported values: "ncc", "rms", where the default is "ncc", or use one of the following:
- --ncc
-
Normalized cross correlation. [This is the default]
- --rms
-
Root of mean squared differences.
- --stdev-thresh <double>
-
Threshold for bad slice identification in units of intensity standard deviations over all corresponding slices from the remaining diffusion images. [Default: 3]
Output Options
- --bad-slices-thresh <none>
-
Minimum number of detected bad slices before reporting a volume (only number of detected bad slices is reported in this case, rather than each slice separately). [Default: 0]
