Introduction
------------
The AAindex is a database of numerical indices representing various physicochemical and biochemical properties of amino acids and pairs of amino acids. The AAindex consists of three sections: AAindex1 for the amino acid index of 20 numerical values, AAindex2 for the amino acid mutation matrix and AAindex3 for the statistical protein contact potentials. All data are derived from published literature [[1]](#references).
This `aaindex` Python software package is a very lightweight way of accessing the data represented in the various AAIndex databases. Minimal requirements and external libraries are required to use the package and any record and its associated data/numerical indices can be accessed in one line. Currently the software supports the AAIndex1 database with plans to include the AAIndex 2 & 3 in the future. The format of an AAIndex1 record can be seen below:

Installation
-----------------
Install the latest version of `aaindex` using pip:
```bash
pip3 install aaindex --upgrade
```
Install by cloning repository:
```bash
git clone https://github.com/amckenna41/aaindex.git
python3 setup.py install
```
Usage
-----
The AAIndex module is made up of three modules for each AAindex database, with each having a Python class of the same name, when importing the package you should import the required database module:
```python
from aaindex import aaindex1
# from aaindex import aaindex2
# from aaindex import aaindex3
```
### Get record from AAIndex1
The AAindex1 class offers diverse functionalities for obtaining any element from any record in the database. The records are imported from a parsed json <em>aaindex_json</em> in the data folder of the package. You can search for a particular record by its index/record code, description or reference. You can also get the index category, and importantly its associated amino acid values:
```python
from aaindex import aaindex1
full_record = aaindex1['CHOP780206'] #get full AAI record
''' full_record ->
{'category': 'sec_struct', 'correlation_coefficients': {}, 'description': 'Normalized frequency of N-terminal non helical region (Chou-Fasman, 1978b)', 'notes': '', 'pmid': '364941', 'references': "Chou, P.Y. and Fasman, G.D. 'Prediction of the secondary structure of proteins from their amino acid sequence' Adv. Enzymol. 47, 45-148 (1978)", 'values': {'-': 0, 'A': 0.7, 'C': 0.65, 'D': 0.98, 'E': 1.04, 'F': 0.93, 'G': 1.41, 'H': 1.22, 'I': 0.78, 'K': 1.01, 'L': 0.85, 'M': 0.83, 'N': 1.42, 'P': 1.1, 'Q': 0.75, 'R': 0.34, 'S': 1.55, 'T': 1.09, 'V': 0.75, 'W': 0.62, 'Y': 0.99}}
'''
#get individual elements of AAIndex record
record_values = aaindex1['CHOP780206']['values']
record_values = aaindex1['CHOP780206'].values
#'values': {'-': 0, 'A': 0.7, 'C': 0.65, 'D': 0.98, 'E': 1.04, 'F': 0.93, 'G': 1.41, 'H': 1.22, 'I': 0.78, 'K': 1.01, 'L': 0.85, 'M': 0.83, 'N': 1.42, 'P': 1.1, 'Q': 0.75, 'R': 0.34, 'S': 1.55, 'T': 1.09, 'V': 0.75, 'W': 0.62, 'Y': 0.99}

record_notes = aaindex1['CHOP780206']['notes']
record_notes = aaindex1['CHOP780206'].notes
#""
record_correlation_coefficient = aaindex1['CHOP780206']['correlation_coefficient']
record_correlation_coefficient = aaindex1['CHOP780206'].correlation_coefficient
#{}
record_pmid = aaindex1['CHOP780206']['pmid']
record_pmid = aaindex1['CHOP780206'].pmid
#364941
record_category = aaindex1['CHOP780206']['category']
record_category = aaindex1['CHOP780206'].category
#sec_struct
```
### Get total number of AAIndex records
```python
#get total number of records in AAI database
aaindex1.num_records()
```
### Get list of all AAIndex record names
```python
#get list of all AAIndex record names
aaindex1.record_names()
```
