-
Data Preprocessing
-
--log, -l -
Apply log to input data
-
--abs, -a -
Use absolute input values
-
--normalize-mean-stdev, -n -

-
--set-padding-value <double> -
Define padding value in input images [Default: disabled]
Output Options
-
--outfile-name <string>, -o <string> -
Output file name [Default: average.nii ]
-
--type -
Scalar data type of output image. Supported values: "float", "double", where the default is "float", or use one of the following:
-
