Installation

pip install pyionics

About package

this package is spesific tool for install datasets from ilthermo.org website and converting to csv, tsv files, merge and adding smiles into data.

WHy you should use this package?

1. property ids update for each updating of ilthermo.org site
2. Converting csv and tsv
3. adding smiles
4. clean dirty json data for converting to other formats
5. merge datasets

Usage

First, import the library in your Python code:

import pyionics as pyi

Retrieve Idsets Data

Use the getIdsets function to retrieve data:

pyi.getIdsets(
    prop="",          # property short name (e.g., 'dens')
    data_path=None,   # optional: path to your data
    cmp="",           # component name (e.g., 'benzene')
    ncmp="0",         # component number: 0=all, 1=pure, 2=binary, 3=triple
    year="",          # publish year
    auth="",          # author name
    keyw=""           # keyword
)

getIdsets Parameters

Parameter	Description	Example
prop	Property short name	dens
cmp	Component name	benzene
ncmp	Component number	1, 2, 3
year	Publish year	2020
auth	Author name	Smith
keyw	Keyword	ionic

• prop: Use the short version of the property name (see below).
• ncmp: 0 = all, 1 = pure, 2 = binary, 3 = triple.

Retrieve Datasets

Use the getData function to retrieve specific datasets.
When you call getData, it will collect all datasets matching your criteria (using getIdsets internally) and save them as JSON files in a newly created data folder in your working directory.

pyi.getData(
    prop=None,        # property short name (e.g., 'dens')
    data_path=None,   # optional: path to your data
    cmp="",           # component name (e.g., 'benzene')
    ncmp="0",         # component number: 0=all, 1=pure, 2=binary, 3=triple
    year="",          # publish year
    auth="",          # author name
    keyw=""           # keyword
)

Note: getData has the same parameters as getIdsets. See the table above for details.

Property List

Only short versions of property names are available for the getIdsets and getData functions.

When you use getIdsets, the output will be saved as a JSON file in a newly created data folder in your working directory. The output file is named as {prop}_idsets_{other parameters}.json, where {prop} is the short property name and {other parameters} reflect your query.

Convert Functions

After retrieving datasets with an idsets request, the data is saved as a JSON file. The pyionics library provides functions to convert these JSON files to CSV or TSV formats using convert2csv and convert2tsv. Note that merging datasets and adding SMILES information require the data to be in CSV format.

Just write the folder name located inside the data folder; do not include data as the parent directory.To convert files, use the following functions:

Convert to CSV:

    pyi.convert2csv(folder_name='', file_name=''):
    # Converts a JSON file to CSV format
    # Only one of the parameters (`folder_name` or `file_name`) is required.

Convert to TSV:
```python
    pyi.convert2tsv(folder_name='', file_name=''):
    # Converts a JSON file to TSV format
    # Only one of the parameters (`folder_name` or `file_name`) is required.

Add SMILES

Note : getSmiles function runs just csv files. Also for folder_name parameter it shoud start with csv_ (other case function do not works right).

    pyi.addSmiles(folder_name='', file_name=''):

Merge datasets

MergeFIles is function to merge datasets in folder

    pyi.mergeFiles(folder_name):
