MINCCOPY(1) MINC User's Guide MINCCOPY(1)NAME
minccopy - copy minc image values from one minc file to another
SYNOPSIS
minccopy [-pixel_values] [-real_values] infile outfile
DESCRIPTION
minccopy copies image values from one minc file to another. Both the input and output files must exist, and the images in both files must
have an equal number dimensions and equal dimension lengths.
By default the real value of each pixel is copied. Use the -pixel_values to copy the pixel values instead.
NOTE: This program is intended primarily for use with scripts such as mincedit. It does not follow the typical design rules of most MINC
command-line tools and therefore should be used only with caution.
OPTIONS -pixel_values Copy voxel values in raw mode.
-real_values Copy voxel intensities (default).
-help Print summary of command-line options and exit.
-version Print version number of program and exit.

mincmakescalar - convert vector minc files to scalar
SYNOPSIS
mincmakescalar [<options>] <in>.mnc <out>.mnc
DESCRIPTION
Mincmakescalar converts vector minc files to scalar minc files. A vector minc file is one that contains the dimension vector_dimension as
the fastest varying dimension of the image data and represents vector data at each voxel such as RGB images or gradient volumes. A scalar
minc file does not contain the vector dimension and represents grayscale or intensity data.
A variety of conversion schemes are possible. The simplest is an average of the components of the vector. The magnitude of the vector at
each voxel can also be computed. RGB volumes can be converted to greyscale by a standard linear combination. Finally, the user can supply a
list of coefficients for a linear combination of vector components.
Some options will require a specific number of components on the input vectors (RGB data should have 3 components and the number of coeffi-
cients supplied for the linear combination should match the number of components on the input vectors), but the program will also accept
input scalar data and will copy it through without modification.
OPTIONS
Note that options can be specified in abbreviated form (as long as they are unique) and can be given anywhere on the command line.
General options-2 Create a MINC 2.0 format output file.
-clobber
Overwrite an existing file.
-noclobber
Don't overwrite an existing file (default).
-no_clobber
Synonym for -noclobber.
-verbose
Print out progress information for each chunk of data copied (default).
-quiet Do not print out progress information.
-buffer_size size
Specify the maximum size of the internal buffers (in kbytes). Default is 10 MB.
-filetype
Create an output file with the same type as the first input file (default).
-byte Store output voxels as 8-bit integers.
-short Store output voxels as 16-bit integers.
-int Store output voxels as 32-bit integers
-long Superseded by -int.
-float Store output voxels as 32-bit floating point numbers.
-double
Store output voxels as 64-bit floating point numbers.
-signed
Create an output file with data stored in a signed type. This only has an effect if the one of the -byte, -short or -int options is
specified.
-unsigned
Create an output file with data stored in an unsigned type. This only has an effect if the one of the -byte, -short or -int options
is specified.
-valid_range min max
Create an output file with integer data stored in the specified restricted range. This only has an effect if the one of the -byte,
-short or -int options is specified.
Conversion options-magnitude
Compute the magnitude of each vector (default).
-average
Compute the average of the components of each vector.
-rgbtogrey
Convert RGB (3-component) files to greyscale using a linear combination with standard set of weighting coefficients.
-rgbtogray
Synonym for -rgbtogrey.
-linear c1,c2,c3,...
Compute a linear combination of the components of each vector using the specified coefficients (these weights must be given as a
comma or space-separated list of numbers in a single command-line argument). The number of coefficients must match the number of
components on the input vectors.
Generic options for all commands:
-help Print summary of command-line options and exit.
-version
Print the program's version number and exit.
EXAMPLES
To convert an RGB file to an grayscale file:
mincmakescalar -rgbtogrey rgb.mnc gray.mnc
To compute the gradient magnitude from a gradient volume
mincmakescalar -magnitude gradient.mnc magnitude.mnc
To convert an RGB file to a grayscale file using a different set of weighting factors for red, green and blue:
mincmakescalar -linear '0.2,0.5,0.3' rgb.mnc gray.mnc
