voids with a watershed algorithm."

Requirements
|
|
------------
|
|
|
|
The package swig needs to be installed and available in the PATH (http://www.swig.org/). It
|
|
is required by scipy and we have not decided to bundle it with VIDE at the moment.
|
|
|
|
|
|
Quick Start Guide
|
|
-----------------
|
|
|
|
After installing the package with `python3 setup.py install --user`, you can execute
|
|
|
|
```
|
|
python3 -m void_pipeline your_config_file.py
|
|
```
|
|
|
|
The VIDE tools are all packaged in the `vide` package.
|
|
|
|
|
|
Running with simulation
|
|
-----------------------
|
|
|
|
!! Temporary measure !!
|
|
|
|
After build the vide package and installing it with `python3 setup.py install` (for example), it is possible to find the
|
|
script to build the pipeline for simulations in `build/temp.[SOMETHING]/pipeline/prepareInputs.py`. Just copy that script where
|
|
you want the analysis and execute it directly with the parameter file as an argument.
|
|
|
|
For example:
|
|
```
|
|
mkdir $HOME/my_vide_test
|
|
cp build/temp.[SOMETHING]/pipeline/prepareInputs.py $HOME/my_vide_test
|
|
cp python_tools/void_pipeline/datasets/example_simulation.py $HOME/my_vide_test
|
|
mkdir $HOME/my_vide_test/examples
|
|
cp examples/example_simulation_z0.0.dat $HOME/my_vide_test/examples
|
|
cd $HOME/my_vide_test
|
|
python3 prepareInputs.py --all --parm example_simulation.py
|
|
python3 -m void_pipeline example_simulation/sim_ss1.0.py
|
|
```
|
|
|
|
Notes for CONDA
|
|
---------------
|
|
|
|
|
|
If you use a conda installation, you have to be sure to use all the building tools that
|
|
are consistent. On linux that means for example installing the conda packages `gcc_linux-64`
|
|
and `gxx_linux-64`. In addition to that it is recommended to define the environment variable
|
|
`LIBRARY_PATH=the_path_of_your_conda_environment_with_/lib`. For example if your environment
|
|
is in '/home/user/conda' you should define
|
|
|
|
```
|
|
export LIBRARY_PATH=/home/user/conda/lib
|
|
```
|
|
|
|
You can then initiate the construction with
|
|
|
|
```
|
|
python3 setup.py build
|
|
```
