Resize an image by defining the new image resolution, voxel size or a scale factor
mrresize [ options ] input output
- input: input image to be resized.
- output: the output image.
Note that if the image is 4D, then only the first 3 dimensions can be resized.
Also note that if the image is down-sampled, the appropriate smoothing is automatically applied using Gaussian smoothing.
- -size dims define the new image size for the output image. This should be specified as a comma-separated list.
- -voxel size define the new voxel size for the output image. This can be specified either as a single value to be used for all dimensions, or as a comma-separated list of the size for each voxel dimension.
- -scale factor scale the image resolution by the supplied factor. This can be specified either as a single value to be used for all dimensions, or as a comma-separated list of scale factors for each dimension.
- -interp method set the interpolation method to use when resizing (choices: nearest, linear, cubic, sinc. Default: cubic).
Data type options¶
- -datatype spec specify output image data type. Valid choices are: float32, float32le, float32be, float64, float64le, float64be, int64, uint64, int64le, uint64le, int64be, uint64be, int32, uint32, int32le, uint32le, int32be, uint32be, int16, uint16, int16le, uint16le, int16be, uint16be, cfloat32, cfloat32le, cfloat32be, cfloat64, cfloat64le, cfloat64be, int8, uint8, bit.
- -info display information messages.
- -quiet do not display information messages or progress status. Alternatively, this can be achieved by setting the MRTRIX_QUIET environment variable to a non-empty string.
- -debug display debugging messages.
- -force force overwrite of output files. Caution: Using the same file as input and output might cause unexpected behaviour.
- -nthreads number use this number of threads in multi-threaded applications (set to 0 to disable multi-threading).
- -help display this information page and exit.
- -version display version information and exit.
