        ### Open Patch Manager: parallel reading/writing of patches.
        
        ## Installation: 
        
        ### For Usage Only
        ```powershell
        conda create -p ./venv python=3.8.12 -y
        conda activate ./venv
        pip install OpenPatchMiner
        ## alternate
        # conda install -c conda-forge openpatchminer
        ```
        
        ### For OPM Development
        ```powershell
        git clone https://github.com/CBICA/OPM.git
        cd OPM/
        conda create -p ./venv python=3.8.12 -y
        conda activate ./venv
        pip install .
        ```
        
        ## Usage
        To try an example:
        ```powershell
        # continue from virtual environment shell
        # Extract 10 tissue patches from images/example_slide.tiff
        python patch_miner.py -i images/example_slide.tiff -lm images/example_lm.tiff -o example -c opm/config.yml
        # Use the output manifest from last run (example/list.csv) to re-extract the same patches for a different replicate
        # This is useful if you have multiple slides/label maps and you want corresponding coordinates from each of them
        python patch_miner.py -i images/example_slide.tiff -lm images/example_lm.tiff -c opm/config.yml -o example_replicate --input_csv example/list.csv
        ```
        By default it detects tissue and extracts 1000 random patches from the included .svs file. Play with this number as well as the number of parallel threads in example.py (default patches=1000, default threads=100)
        ## Options
        There are also a handful of useful options:
        - `READ_TYPE`: either 'sequential' or 'random'. If sequential, it repeatedly takes the top-leftmost valid index until quota is met or the slide is saturated. If random, it randomly samples a patch from the valid indices until saturated or the quota is hit.
        
        ... and various other parameters such as patch size, thumbnail/valid mask scale, and masking thresholds.
        
        ## Workflow
        OPM follows the following workflow:

        ## Changelog
        Dec. 14, 2021:
        - Replaced slide library with tifffile
        - Made barebones OpenSlide mimic with tifffile, named SlideObject
        - Updated requirements, bumped minimum python from 3.6 --> 3.8 (due to zarr requirements)
        - Updated README
        
        
        Dec. 9, 2021:
        - Changed backend to Pandas.
        - Updated README
        
        Nov. 17, 2020:
        - Added support for mining patches from label map along with the slide.
        - Updated README
        
        Jul. 31, 2020:
        - Changed `ALLOW_OVERLAP` to `OVERLAP_FACTOR`. `OVERLAP_FACTOR` is a float from 0 to 1 that is the portion of patches that are allowed to overlap. If 0, there is no overlap allowed. If 1, they are totally allowed to overlap (except for the origin pixel).
