raw2mrc(1) General Commands Manual raw2mrc(1) NAME raw2mrc - Create an MRC image stack from raw image data. SYNOPSIS raw2mrc [options] raw_image_files... MRC_output_file DESCRIPTION raw2mrc can be used to create MRC image stacks from many types of raw binary image data. Command line options are used to specify the image size and to skip the input image header. Several raw images can be combined into one file by listing all of their filenames before the name of the output file, or providing them with multiple entries of the -input option. The environment variable IMOD_OUTPUT_FORMAT can be set to produced TIFF or HDF output. OPTIONS Raw2mrc uses the PIP package for input (see the manual page for pip). Options can be specified either as command line arguments (with the -) or one per line in a command file (without the -). Options can be abbreviated to unique letters; the currently valid abbreviations for short names are shown in parentheses. -input (-in) OR -InputFile File name Input image file. Input files may also be entered after all arguments on the command line. Files entered with this option will be processed before files at the end of the command line, if any. (Successive entries accumulate) -output (-ou) OR -OutputFile File name Output image file. If this entry is omitted, the last non- option argument will be used for the output filename; otherwise, all non-option arguments will be used as input filenames. -x OR -XSize Integer Set the width of the image; this entry is required -y OR -YSize Integer Set the height of the input image; this entry is required -z OR -SectionsPerFile Integer Set the number of sections in each input image file, the default is 1. -t OR -DataType Text string Set the type of input data; the default is byte data. The allowed types are byte, short, ushort, long, ulong, float, dou- ble, and rgb. Where byte is 8-bit integer values, short is 16-bit signed values, ushort is 16-bit unsigned values, long is 32-bit signed values, ulong is 32-bit unsigned values, float and double are 32-bit and 64-bit floating point values and rgb is three byte values--one for each color. -s OR -SwapBytes Swap input bytes. Does not work for doubles. -o OR -OffsetToImageData Integer Set the offset value used at the beginning of the file, the default is 0. -oz OR -SkipBetweenSections Integer Set the offset value used at the end of each section, the default offset is 0. -f OR -FlipInY Flip the images around the X axis. -i OR -InvertInZ Produce an inverted output stack by both inverting the order in which files are processed and inverting the order of reading Z slices from each file. -iz OR -ReadInvertedInZ Invert the order of reading Z slices from each individual file. -d OR -DivideBy2 Divide unsigned 16-bit values by 2, or divide any 32-bit inte- gers or 64-bit doubles being converted to 16 bits by 2. The default for unsigned short values is to subtract 32767, which allows all unsigned short values to be stored as signed short integers in the MRC file of mode 1. Use this option if you do not want negative numbers and do not care about the loss of pre- cision. If the values in the input files are all less than 32768, then specify that the input data are short rather than ushort. -u OR -UnsignedOutput Store unsigned 16-bit values without modification in an MRC file of mode 6; or store doubles in mode 6 if the -c option is given also. -c OR -ConvertTo16BitInt Convert 32-bit integers or 64-bit doubles to 16-bit integers instead of to 32-bit floating-point numbers. If the type is long, you can use this option alone if values are between -32768 and 32767; or you can use the option with .B -d to divide by 2 if values are between -65536 and 65535. If you specify the type as ulong, then by default 32767 will be subtracted from the input values, so that values from 0 to 65534 can be stored as -32767 to 32767. Again, .B -d can be used to divide by 2 instead, so that values from 0 to 65534 can be stored as 0 to 32767. Also, .B -u can be used to store the numbers as unsigned integers in a file of mode 6. Thus, doubles with a range of 0 to 131070 can be stored as unsigned 16-bit values using all of -c, -d, and -u. If values in the input files are all less than 32768, then specify the type as long instead of ulong. -p OR -PixelSpacing Floating point Set the pixel spacing of the MRC file header to the given value, which should generally be a pixel size in Angstroms. -pz OR -ZPixelSpacing Floating point Set the Z pixel spacing of the MRC file header to the given value if it is different from the one given with the .B -p option. -help (-h) OR -Usage Print help output -StandardInput Read parameter entries from standard input FILES If the output file already exists, it will be made a backup file by adding ~ to its name.
