This is yt_astro_analysis, the [yt](https://github.com/yt-project/yt) extension
package for astrophysical analysis.  This is primarily machinery that used to be
in yt's analysis_modules.  These were made into a separate package to allow yt to
become less astro-specifc and to allow these modules to be developed on their own
schedule.

## Installation

To install yt_astro_analysis, you will first need to 
[install yt](https://github.com/yt-project/yt#installation). Then do,

```
$ pip install yt_astro_analysis
```

If you use conda, do,

```
$ conda install -c conda-forge yt_astro_analysis
```

If you would like to build `yt_astro_analysis` from source, clone the git
repository and install like this:

```
git clone https://github.com/yt-project/yt_astro_analysis
cd yt_astro_analysis
pip install -e .
```

### Installing with Rockstar support

In order to run the Rockstar halo finder from within yt_astro_analysis, you will
need to install the
[yt-project's fork of Rockstar](https://github.com/yt-project/rockstar) and then
provide this path to yt_astro_analysis.  To install Rockstar, do the following:

```
git clone https://github.com/yt-project/rockstar
cd rockstar
make lib
```

Then, go into the yt_astro_analysis source directory and add a file called
"rockstar.cfg" with the path the Rockstar repo you just cloned.  Then, install
yt_astro_analysis.

```
cd yt_astro_analysis
echo  > rockstar.cfg
pip install -e .
```

Finally, you'll need to make sure that the location of ``librockstar.so`` is in
your LD_LIBRARY_PATH.

```
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:
```

## Importing from yt_astro_analysis

For every module that was moved from yt's analysis_modules to yt_astro_analysis,
all imports can be changed simply by substituting ``yt.analysis_modules`` with
``yt.extensions.astro_analysis``.  For example, the following

```
from yt.analysis_modules.ppv_cube.api import PPVCube
```
becomes
```
from yt.extensions.astro_analysis.ppv_cube.api import PPVCube
```

## Contributing

We really want your contributions!  As an official
[yt-project](http://yt-project.org/) extension, everything in the
[yt Contributor Guide](https://github.com/yt-project/yt#contributing) applies
here.

If you'd rather make your own standalone package, we want to support that, too!
Please, consider making your package a
[yt extension](http://yt-project.org/extensions.html).

## Resources

As an extension of the [yt-project](http://yt-project.org/), the
[yt resources](https://github.com/yt-project/yt#resources) are available for help.
