Update README

Collection of scripts to run analysis of LST data at the IT cluster in La Palma.

The repository contains also a folder with some bash scripts that can be easily used.

## Analysis tree

Use `create_analysis_tree.py` to create automatically a directory tree.

The default one is:

```bash

Parent_Folder

        └──DL1

            ├── source

            │   └── night

            │      └── version

            │           └── cleaning

            DL2

            ├── source

            │   └── night

            │      └── version

            │           └── cleaning

            DL3

            └── source

                └── night

                   └── version

                        └── cleaning

```

Modify the script at your convenience if you prefer a different structure.

Change the default value for the Parent folder in the argparse with your own path.

Example:

```bash

python create_analysis_tree.py --source Crab --night 20220304

```

Output:

```bash

Directory  /fefs/aswg/workspace/alice.donini/Analysis/data/DL1/Crab/20220304/v0.9.2/tailcut84  already exists

Directory  /fefs/aswg/workspace/alice.donini/Analysis/data/DL2/Crab/20220304/v0.9.2/tailcut84  Created

Directory  /fefs/aswg/workspace/alice.donini/Analysis/data/DL3/Crab/20220304/v0.9.2/tailcut84  Created

Directory structure ready for analysis on Crab.

```
