flower_map

A pipeline for generating maps of the species of flowers around a bee colony using drone imagery. The pipeline uses Agisoft Metashape to stitch the drone images together into an orthomosaic, various computer vision algorithms to segment each plant from its background, and a pre-trained random forest classifier to label each plant by its species.

download

Execute the following commands or download the latest release manually.

git clone https://github.com/beelabhmc/flower_map.git

setup

dependencies

The pipeline is written as a Snakefile which can be executed via Snakemake. We recommend using version 5.20.1 for reproducibility:

conda create -n snakemake -c bioconda -c conda-forge --no-channel-priority 'snakemake==5.20.1'

We highly recommend you install Snakemake via conda like this so that you can use the --use-conda flag when calling snakemake to let it automatically handle all dependencies of the pipeline. Otherwise, you must manually install the dependencies listed in the env files.

Agisoft Metashape

Our Snakefile assumes that there is a metashape.lic file containing the Metashape License in the same directory as the run.bash script. Without this file, the pipeline will attempt to run Metashape unlicensed, which usually fails on import. To create the file, run the following command after activating your snakemake conda environment:

metashape_LICENSE="your-25-digit-license-key-goes-here" ./run.bash -U create_license

execution

  1. Activate snakemake via conda:

    conda activate snakemake
    
  2. Execute the pipeline

    Locally:

    ./run.bash &
    

    or on an SGE cluster:

    qsub run.bash
    

Log files describing the output of the pipeline will be created within the output directory. The log file contains a basic description of the progress of each rule, while the qlog file is more detailed.

Executing the pipeline on your own data

You must modify the config.yaml file to specify paths to your data. See our wiki for more information.

If this is your first time using Snakemake

We recommend that you run snakemake --help to read about Snakemake's options. For example, to check that the pipeline will be executed correctly before you run it, you can call Snakemake with the -n -p -r flags. This is also a good way to familiarize yourself with the steps of the pipeline and their inputs and outputs (the latter of which are inputs to the first rule in the pipeline -- ie the all rule).

Note that Snakemake will not recreate output that it has already generated, unless you request it. If a job fails or is interrupted, subsequent executions of Snakemake will just pick up where it left off. This can also apply to files that you create and provide in place of the files it would have generated.

files and directories

A Snakefile for running the entire pipeline. It uses overlapping drone imagery to create a map of the species of flowers surrounding a bee colony.

A config file that define options and input for the pipeline. You should start by filling this out.

Various scripts used by the pipeline. See the script README for more information.

An example bash script for executing the pipeline using snakemake and conda. Any arguments to this script are passed directly to snakemake.
