A Monte Carlo to Hessian conversion tool for PDF sets.

For the Genetical Algorithm methodology please visit the [gamethod branch](https://github.com/scarrazza/mc2hessian/tree/gamethod)

## Download

Download the latest [release](https://github.com/scarrazza/mc2hessian/releases) or clone the master development repository by running the following command:

```Shell

$ git clone https://github.com/scarrazza/mc2hessian.git

```

## Installation

This program requires python3, numpy, pandas and

LHAPDF6. [LHAPDF](https://lhapdf.hepforge.org/) needs to be installed

and working correctly with the python environment. If you prefer the

simplest way to install all required packages is using the

[Anaconda](https://store.continuum.io/cshop/anaconda/) distribution.

Note that the installer script does not check for dependencies. This

will install the `mc2hessian` program and the `mc2hlib` Python library

in the appropriate paths.

## Usage

```Shell

$./mc2hessian --help

usage: mc2hessian [-h] [--epsilon EPSILON] [--no-grid] [pdf_name] [nrep] [Q]

positional arguments:

  pdf_name           Name of LHAPDF set

  nrep               Number of basis vectors

  Q                  Energy scale.

optional arguments:

  -h, --help         show this help message and exit

  --epsilon EPSILON  Minimum ratio between one sigma and 68% intervals to

                     select point.

  --no-grid          Do NOT compute and save the LHAPDF grids. Output the

                     error function only

```

The output of this script is a hessian set of PDF in the LHAPDF6 format.
