mincsample - generate samplings from minc files.
mincsample [<options>] <in1.mnc>
[<in2.mnc> [<..>]]
Mincsample produces a data sampling on STDOUT from an input
series of minc files. The output can be either ascii (-ascii) or as a raw
binary stream of doubles (-double). The output data is ordered first by file
then voxel. When -ascii is used the data values from each file are separated
by a tab and the sampling points with a newline. When using -double, no
separators are used.
If -coords is also specified, the world co-ordinate at each
sampling point will precede the data from each of the files. An optional
-outfile argument can also be used to direct the output to a file and
-append used to append the data to the file as opposed to overwriting the
file.
By default all data points are written out (-all) the output of
points can also be constrained to be points within a mask (-mask and
-mask_val) and further by a random sampling of a sub-set of points via the
-random_samples and -random_seed arguments
- -verbose
- Print extra information during processing.
- -quiet
- Print only the output sampling data.
- -clobber
- Overwrite existing output files (when used with -outfile)
- -max_buffer
size
- Specify the maximum size of the internal buffers (in kbytes). Default is
4096 (4MB).
- -mask
mask.mnc
- Specify and input mask, only sampling points within this mask will be
used.
- -mask_val
value
- Specify the value to use from the mask (Default: 1).
- -all
- Sample all the data points.
- -random_seed
value
- Specify the random seed value to use during random sampling, this is to
enable reproducible runs. If no seed is given a semi-random seed will be
chosen (from time).
- -random_samples
value
- Specify the number of random samples to take from the input files. This
value must be smaller than the maximum possible number of samples.
- -sample
sample.mnc
- Output a mask file that corresponds to where samples were taken from.
- -outfile
file
- Output sampling data to a file. (Default: STDOUT).
- -append
- Append output data to an existing file.
- -ascii
- Write out data as ascii strings (Default).
- -ascii
- Write out data as double precision floating-point values.
- -coords
- Write out world co-ordinates as well as sampling values.
- -help
- Print summary of command-line options and exit.
- -version
- Print the program's version number and exit.
