BiopTort

BiopTort is a tool designed for quantifying tortuosity in core needle biopsies. Tortuosity is a measure of the twisting and turning of the biopsy path, and is a common yet largely unreported artifact in pathology.

Features

BiopTort produces two types of output:

1. A .pptx file where each slide displays the qualitative BiopTort output:

2. A .csv file containing quantitative metrics extracted for each slide:

Installation

Using Docker

docker run -v <YOUR_DATA_PATH>:/data -it jacksonjacobs1/bioptort:main /bin/bash

Usage

BiopTort exposes the following CLI options:

$ python3 -m bioptort --help
usage: __main__.py [-h] --im_path IM_PATH --ppt_save PPT_SAVE [--csv_save CSV_SAVE] [--mask_path MASK_PATH] [--sort] [--gauss_sigma GAUSS_SIGMA]

options:
  -h, --help            show this help message and exit
  --im_path IM_PATH     The directory containing (openslide-compatible) CNB WSIs.
  --ppt_save PPT_SAVE   The path to save the powerpoint presentation, including the filename.
  --csv_save CSV_SAVE   Optional path to save a csv file containing quantitative results, including the filename.
  --mask_path MASK_PATH
                        Optional path to existing png tissue masks for the CNB WSIs with matching filenames.
  --sort, -s            Sort the slides in order of highest to lowest tortuosity.
  --gauss_sigma GAUSS_SIGMA
                        The sigma value for the gaussian filter.

python3 -m bioptort --im_path /data/ --ppt_path /data/<YOUR_PPT_NAME>.pptx --csv_path /data/<YOUR_CSV_NAME>.csv
