mcd-stitcher 2.0.0

MCD to single tiffs, stitched tiff and tiff tools

MCD STITCHER

MCD Stitcher is a high-performance Python package designed to streamline the processing of Imaging Mass Cytometry (IMC) data. It simplifies the conversion of .mcd files into standards-compliant OME-TIFFs, handles ROI stitching, and provides tools for channel subsetting, pyramid generation and OME-TIFF compression.

Key Features

• Convert: Fast transformation of MCD files to OME-TIFF.
• Stitch: Automatic whole-slide reconstruction from ROIs.
• Optimize: Channel filtering and pyramidal OME-TIFF generation for smooth viewing in QuPath, Napari, and ImageJ.

Installation

MCD Stitcher requires Python 3.11 or higher.

To install the package, use the following command:

pip install mcd_stitcher

⚡ Workflow Commands

▶️ MCD_STITCH

Description: Converts all ROIs from MCD files into whole-slide stitched OME-TIFFs.

Command:

mcd_stitch <input_path> [<output_path>] [OPTIONS]

Arguments:

• input_path: Path to an MCD file or a folder containing .mcd files.
• output_path: (Optional) Output folder for stitched OME-TIFFs. Defaults to: <input_path>/TIFF_stitched.

Options:

• -d, --output_type [uint16 | float32]: Output pixel data type. Default: uint16
• -c, --compression [None | LZW | zstd]: Compression method for the output OME-TIFFs. Default: zstd

Example:

1. Stitch with default output folder and options

   mcd_stitch "/path/to/MCD_folder"
   

2. Stitch with custom output folder and options

   mcd_stitch "/path/to/MCD_folder" "/path/to/TIFF_stitched" -d float32 -c None
   

▶️ MCD_CONVERT

Description: Converts all ROIs from input MCD files into individual OME-TIFFs.

Command:

mcd_convert <input_path> [<output_path>] [OPTIONS]  

Arguments:

• input_path: Path to an MCD file or a folder containing .mcd files.
• output_path: (Optional) Output folder for stitched OME-TIFFs. Defaults to: <input_path>/TIFF_Converted.

Options:

• -d, --output_type [uint16 | float32]: Output pixel data type. Default: uint16
• -c, --compression [None | LZW | zstd]: Compression method for the output OME-TIFFs. Default: zstd

Example:

1. Convert with default output folder and options

   mcd_convert "/path/to/MCD_folder"
   

2. Convert with custom output folder and options

   mcd_convert "/path/to/MCD_folder" "/path/to/TIFF_Converted" -d float32 -c LZW
   

▶️ TIFF_SUBSET

Description: Subsets channels from OME-TIFF files, with options to list channels, filter specific channels, and generate pyramidal OME-TIFF outputs.

Command:

tiff_subset <input_path> [OPTIONS]

Arguments:

• input_path: Path to an OME-TIFF file or a directory containing OME-TIFF files.

Options:

• -d, --output_type [uint16 | float32]: Output pixel data type. Default: uint16
• -c, --compression [None | LZW | zstd]: Compression method for the output OME-TIFFs. Default: zstd
• -l, --list-channels: List all channels in the input OME-TIFF.
• -f, --filter "CHANNELS": Subset channels using a range or list (e.g. "0-5,7,10").
• -p, --pyramid: Create a pyramidal (tiled) OME-TIFF output.

Examples:

1. List all channels in an OME-TIFF file:

   tiff_subset "path/to/file.ome.tiff" -l
   

2. Subset channels 12 to 46 in an individual OME-TIFF:

   tiff_subset "path/to/file.ome.tiff" -f "12-46"
   

   Note: Other possible combinations: "1,6,20" or "5,6-10,55,60"

3. Subset channels in all OME-TIFFs in a directory 12 to 46

   tiff_subset "path/to/directory" -f "12-46"
   

   Note: The output files will have _filtered.ome.tiff appended to the original filename.

4. Convert an OME-TIFF file into pyramid OME-TIFF

   tiff_subset "path/to/file.ome.tiff" -p	
   

   Note: The output files will have _pyramid.ome.tiff appended to the original filename.

5. Subset channels and generate pyramid OME-TIFF:

   tiff_subset "path/to/file.ome.tiff" -p -f "12-46"
   

   Note: The output files will have _filtered_pyramid.ome.tiff appended to the original filename.
