# 4. PostMØD (mod_post)¶

The post processor, mod_post, is used for compiling figures and a summary document of the data in the out/ folder. As default it is automatically invoked by the wrapper script.

The script does the following:

1. Clear the folder summary. If it does not exist, it is created.
2. Source the file out/post.sh and create summary/Makefile.
3. Run make -f summary/Makefile all (with a few more arguments). The Makefile will compile figures and generate a Latex file. A master Latex docuemnt is compiled to summary/summary.pdf. The master document includes the generated Latex file.

## 4.1. Usage¶

mod_post [options]


### 4.1.1. Options¶

--help, -h

Shows the help output of the script.

-j <N>

When running make, use -j <N> as additional arguments. This parameter defaults to 2.

### 4.1.2. Environtment Variables¶

MOD_NUM_POST_THREADS

If defined, the value of this variable is used for -j when invoking make. When -j <N> is given to the script, this variable is ignored.

## 4.2. Useful API References¶

The API of libMØD and PyMØD includes functionality for injecting code and modifying the behaviour of PostMØD and generated summaries. See libMØD (Misc.h) and PyMØD (Misc) for the documentation of these functions.
