A package made for stitching ROIs into OME-TIFFS and additional OME-TIFF editing tools

To install the package, use the following command:

pip install mcd_stitcher

The following dependencies will installed:

• click
• numpy
• pandas
• python_dateutil
• xarray
• zarr
• scikit-image

Command:

imc2zarr <mcd_folder> <zarr_folder>

Description: Converts MCD files to Zarr format.

Arguments:

• mcd_folder: The root folder of the IMC scan containing single or multiple MCD files.
• zarr_folder: (Optional) Storage location of converted MCD files in Zarr format. If not provided, the output folder <mcd_folder>/Zarr_converted will be automatically created.

Notes:

• The Zarr output folders are named after the MCD file names.
• Progress and errors will be printed to the console for better monitoring.

Command:

zarr_stitch <zarr_folder>

Description: Stitches Zarr files into a multi-channeled OME-TIFF.

Arguments:

• zarr_folder: The folder containing Zarr files to be stitched.

Notes:

• The <zarr_folder> should only contain folders with Zarr data. Empty or unexpected folder structures will be skipped.
• Errors encountered during processing will be logged to error_log.txt in the input directory.
• The output files will have _stitched.ome.tiff appended to the original filename.
• Success messages will be printed for each processed folder.

Command:

mcd_stitch <mcd_folder> [<zarr_folder>] [--lzw]

Description: Combines the MCD to Zarr conversion and Zarr stitching into a single command.

Arguments:

• mcd_folder: The root folder of the IMC scan containing single or multiple MCD files.
• zarr_folder: (Optional) Storage location of converted MCD files in Zarr format and the starting point for stitching Zarr files. If not provided, the output folder <mcd_folder>/Zarr_converted will be automatically created.
• --lzw: Optional flag to enable LZW compression.

Command:

tiff_subset <tiff_path> [-c] [-f CHANNELS] [-p]

Description: A function that allows you to remove background channels, view all channels in an OME-TIFF, and generate OME-TIFF with pyramid and tiles.

Arguments:

• tiff_path: Path to the OME-TIFF file or directory containing OME-TIFF files.
• -c: Lists all channels in the OME-TIFF file.
• -f CHANNELS: Filters and subsets channels. Provide channels to subset, e.g., "0-5,7,10". If no channels are provided, default filtering is applied.
• -p: Enables the creation of a pyramidal OME-TIFF with tiling.

Notes:

• Default filtering: Automatically subsets all channels for metals tags between 141 to 193.
• Pyramid and Tiling: The hardcoded tile size is (256x256) and pyramid levels as 4.
• Errors encountered during processing will be logged to error_log.txt in the input directory.

Examples:

1. List channels in a TIFF file:

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

2. Subset channels 12 to 46:

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

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

3. Subset all TIFF files in a directory:

   tiff_subset "path/to/directory" -f
   

   Notes:

   • In this example, since no channel argument is provided, the function will automatically use default filtering.
   • When a directory is provided, all TIFF files within the directory will be processed.
   • The output files will have _filtered.ome.tiff appended to the original filename.

4. Subset Tiff files with Pyramid and Tile Generation:

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

   Notes:

   • This will create a pyramidal OME-TIFF with default filtering.
   • The output files will have _filtered_pyramid.ome.tiff appended to the original filename.
