        ==================
        
        Quick Overview
        --------------
        
        -  Convert DICOM or NIfTI to jpg or png
        
        Overview
        --------
        
        ``med2image`` is a simple Python3 utility that converts medical image
        formatted files to more visual friendly ones, such as png and jpg.
        
        Currently, NIfTI and DICOM input formats are understood, while any
        graphical output type that is supported by matplotlib can be generated.
        
        Dependencies
        ------------
        
        Make sure that the following dependencies are installed on your host
        system (or even better, a python3 virtual env):
        
        -  ``pfmisc`` (a general miscellaneous module for color support, etc) 
        -  ``nibabel`` (to read NIfTI files)
        -  ``pydicom`` (to read DICOM files)
        -  ``matplotlib`` (to save data in various image formats)
        -  ``pillow`` (to save data in jpg format)
        
        Installation
        ~~~~~~~~~~~~
        
        The best method of installing this script and all of its dependencies is
        by fetching it from PyPI
        
        .. code:: bash
        
                pip3 install med2image
        
        Should you get an error about `python3-tk` not installed, simply do (for example on Ubuntu):
        
        .. code:: bash
        
                sudo apt-get update
                sudo apt-get install -y python3-tk
        
        
        Command line arguments
        ----------------------
        
        ::
        
                -i|--inputFile <inputFile>
                Input file to convert. Typically a DICOM file or a nifti volume.
        
                [-d|--outputDir <outputDir>]
                The directory to contain the converted output image files.
        
                -o|--outputFileStem <outputFileStem>
                The output file stem to store conversion. If this is specified
                with an extension, this extension will be used to specify the
                output file type.
        
                SPECIAL CASES:
                For DICOM data, the <outputFileStem> can be set to the value of
                an internal DICOM tag. The tag is specified by preceding the tag
                name with a percent character '%', so
        
                    -o %ProtocolName
        
                will use the DICOM 'ProtocolName' to name the output file. Note
                that special characters (like spaces) in the DICOM value are
                replaced by underscores '_'.
        
                Multiple tags can be specified, for example
        
                    -o %PatientName%PatientID%ProtocolName
        
                and the output filename will have each DICOM tag string as
                specified in order, connected with dashes.
        
                A special %inputFile is available to specify the input file that
                was read (without extension).
        
                [-t|--outputFileType <outputFileType>]
                The output file type. If different to <outputFileStem> extension,
                will override extension in favour of <outputFileType>.
        
                [-s|--sliceToConvert <sliceToConvert>]
                In the case of volume files, the slice (z) index to convert. Ignored
                for 2D input data. If a '-1' is sent, then convert *all* the slices.
                If an 'm' is specified, only convert the middle slice in an input
                volume.
                
                [-f|--frameToConvert <sliceToConvert>]
                In the case of 4D volume files, the volume (V) containing the
                slice (z) index to convert. Ignored for 3D input data. If a '-1' is 
                sent, then convert *all* the frames. If an 'm' is specified, only 
                convert the middle frame in the 4D input stack.
        
                [--showSlices]
                If specified, render/show image slices as they are created.
        
                [--reslice]
                For 3D data only. Assuming [i,j,k] coordinates, the default is to save
                along the 'k' direction. By passing a --reslice image data in the 'i' and
                'j' directions are also saved. Furthermore, the <outputDir> is subdivided into
                'slice' (k), 'row' (i), and 'col' (j) subdirectories.

        NIfTI conversion
        ----------------
        
        Both 3D and 4D NIfTI input data are understood. In the case of 4D NIfTI,
        a specific frame can be specified in conjunction with a specific slice
        index. In most cases, only a slice is required since most NIfTI data is
        3D. Furthermore, all slices can be converted, or just the middle one.
        
        Examples
        ~~~~~~~~
        
        All slices in a volume
        ~~~~~~~~~~~~~~~~~~~~~~
        
        To convert all slices in an input NIfTI volume called vol.nii, to save
        the results in a directory called out and to use as output the file stem
        name image, do
        
        ``med2image -i vol.nii -d out -o image.jpg -s -1``
        
        or equivalently and more verbosely,
        
        ::
        
            med2image --inputFile vol.nii     --outputDir out      \
                      --outputFileStem image  --outputFileType jpg \
                      --sliceToConvert -1
        
        This will create the following files in out
        
        ::
        
            image-slice000.jpg
            image-slice001.jpg
            image-slice002.jpg
            image-slice003.jpg
            image-slice004.jpg
            image-slice005.jpg
            image-slice006.jpg
            image-slice007.jpg
            ...
            image-slice049.jpg
            image-slice050.jpg
            image-slice051.jpg
            image-slice052.jpg
            image-slice053.jpg
        
        Convert only a single slice
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        Mostly, you'll probably only want to convert the "middle" slice in a
        volume (for example to generate a representative thumbnail of the
        volume). To do this, simply specify a m to --sliceToConvert
        
        ``med2image -i input.nii -o input.jpg -s m``
        
        or, again, slightly more verbosely and with an outputDirectory specifier
        
        ``med2image -i input.nii -d out -o vol --outputFileType jpg --sliceToConvert m``
        
        Alternatively a specific slice index can be converted. Use
        
        ``med2image -i input.nii -d out -o vol --outputFileType jpg --sliceToConvert 20``
        
        to convert only the 20th slice of the volume.
        
        DICOM conversion
        ----------------
        
        Convert a single DICOM file
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        To convert a single DICOM file called slice.dcm to slice.jpg, do:
        
        ``med2image -i slice.dcm -o slice.jpg``
        
        which will create a single file, slice.jpg in the current directory.
        
        Convert all DICOMS in a directory/series
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        To convert all the DICOMS in a directory, simply specifiy a '-1' to the
        sliceIndex:
        
        ``med2image -i inputDir/slice.dcm -d outputDir -o slice.jpg -s -1``
        
        Note that this assumes all the DICOM files in the directory inputDir
        belong to the same series.
        
        Multiple Direction Reslicing
        ----------------------------
        
        By default, only the slice (or slices) in the acquisition direction are
        converted. However, by passing a -r to the script, all dimensions are
        converted. Since the script does not know the anatomical orientation of
        the image, the directions are simply labeled x, y, and z.
        
        The z direction is the original acquistion (slice) direction, while x
        and y correspond to planes normal to the row and column directions.
        
        Converted images are stored in subdirectories labeled x, y, and z.
