intervality

This package implements in C++ the functions needed to order diet items in a predator-prey food web such that all diets are maximally contiguous (Stouffer et al. 2006), or determine the contiguity when diet items are ordered based on some known quantity (e.g., mass; Stouffer et al. 2011). As input, both methods require a file listing all predator-prey interactions, and the second requires a paired list of species and their trait value to order on. Full details of the algorithm are available at:

Build instructions

After cloning the repository, you can build the executables by running:

sudo apt-get install autoconf libtool
autoreconf --install
./configure
make

This produces:

  • src/minimumIntervality. This executable uses simulated annealing to determine the minimum possible number of gaps (aka intervality).

  • src/massIntervality. This executable orders diet items based on specified values and returns the corresponding intervality.

You can view the options of any of these scripts with the --help flag.

Usage

To compute the minimum intervality of an interaction matrix, users should run the minimumIntervality executable with something like this:

./src/minimumIntervality -f path/to/net.dat

where path/to/net.dat is a text file that stores the interaction information. By default, minimumIntervality assumes that the interactions will be in a format similar to data/net.dat, and that the first column corresponds to integer labels for predators and the second column to integer labels for prey.

To compute the intervality of an interaction matrix when ordering diets by a pre-defined measure, users should run the massIntervality executable with something like this:

./src/massIntervality -f path/to/net.dat -m path/to/masses.dat

where path/to/net.dat is a text file that stores the interaction information. By default, massIntervality assumes that the interactions will be in a format similar to data/net.dat, and that the first column corresponds to integer labels for predators and the second column to integer labels for prey. It also assumes that all species will be provided a corresponding mass/trait in a format similar to data/masses.dat, and that the first column corresponds to the species' unique integer label and the second column to the continuous valued trait.

where path/to/net.dat is a text file that stores the interaction information. By default, massIntervality assumes that the interactions will be in a
format similar to data/net.dat, and that the first column corresponds to integer labels for predators and the second column to integer labels for prey. It also assumes that all species will be provided a corresponding mass/trait in a format similar to data/masses.dat, and that the first column corresponds to the species' unique integer label and the second column to the continuous valued trait.

intervality
This package implements in C++ the functions needed to order diet items in a predator-prey food web such that all diets are maximally contiguous
(Stouffer et al. 2006), or determine the contiguity when diet items are ordered based on some known quantity (e.g., mass; Stouffer et al. 2011). As input, both methods require a file listing all predator-prey interactions, and the second requires a paired list of species and their trait value to order on. Full details of the algorithm are available at:

Build instructions
After cloning the repository, you can build the executables by running:
sudo apt-get install autoconf libtool
autoreconf --install
./configure
make

This produces:
  • src/minimumIntervality. This executable uses simulated annealing to determine the minimum possible number of gaps (aka intervality).
  • src/massIntervality. This executable orders diet items based on specified values and returns the corresponding intervality.
You can view the options of any of these scripts with the --help flag.
Usage
To compute the minimum intervality of an interaction matrix, users should run the minimumIntervality executable
with something like this:
./src/minimumIntervality -f path/to/net.dat
where path/to/net.dat is a text file that stores the interaction information. By default, minimumIntervality assumes that the interactions will be in a
format similar to data/net.dat, and that the first column corresponds to integer labels for predators and the second column to integer labels for prey.
To compute the intervality of an interaction matrix when ordering diets by a pre-defined measure, users should run the massIntervality executable
with something like this:
./src/massIntervality -f path/to/net.dat -m path/to/masses.dat
where path/to/net.dat is a text file that stores the interaction information. By default, massIntervality assumes that the interactions will be in a
format similar to data/net.dat, and that the first column corresponds to integer labels for predators and the second column to integer labels for prey. It also assumes that all species will be provided a corresponding mass/trait in a format similar to data/masses.dat, and that the first column corresponds to the species' unique integer label and the second column to the continuous valued trait.
