Boulder Laboratory for 3-Dimensional Electron Microscopy of Cells BINVOL(1) BINVOL(1) NAME binvol - Bin a 3D volume down isotropically or anisotropically SYNOPSIS binvol [-b #] input_file output_file DESCRIPTION Binvol will bin down a volume in all three dimensions, with the binning done isotropically or by different amounts in X, Y, and Z. Binning means summing (actually averaging) all of the values in a block of voxels (e.g., 2x2x2 or 1x1x3) in the input volume to create one voxel in the output volume. The output file will have appropriately larger pixel spacings in its header. Binvol uses the PIP package for input (see the manual page for pip). The following options can be specified either as command line arguments (with the -) or one per line in a command file (without the -): -input OR -InputFile File name Input image file to bin down in 3D -output OR -OutputFile File name Output file for binned volume -binning OR -BinningFactor Integer Overall reduction factor to bin by (default 2) -xbinning OR -XBinningFactor Integer Factor to bin by in X (default same as overall factor) -ybinning OR -YBinningFactor Integer Factor to bin by in Y (default same as overall factor) -zbinning OR -ZBinningFactor Integer Factor to bin by in Z (default same as overall factor) -test OR -TestLimit Integer To test the code for reading in and binning in chunks, enter a limit for the total size of the working array. -help OR -usage Print help output -StandardInput Read parameter entries from standard input.
