=============================

[![Gitter](https://badges.gitter.im/Join Chat.svg)](https://gitter.im/TApplencourt/EMSL_Basis_Set_Exchange_Local?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
|
|
|
|
Create of Local Copy of the famous [EMSL Basis Set Exchange](https://bse.pnl.gov/bse/portal) and use it easily with the API.
|
|
|
|
* Make a slight copy (40Mo Sqlite3 database) of the EMSL Basis Set Exchange website. Currently avalaible format are :
|
|
* Gamess-us, Gaussian94 and NEWCHEM;
|
|
* API for scripting;
|
|
* Quick local access without delay;
|
|
* Only need [Python](https://www.python.org/)
|
|
|
|
##Dependencies
|
|
* Python >2.6
|
|
|
|
###### Optional
|
|
If you plan to download manually some database -not using the pre existing one- you need :
|
|
* [Request](http://docs.python-requests.org/en/latest/) python module. ```$pip install requests``` (do it in a virtual env or with sudo)
|
|
|
|
##Installation
|
|
* Download the git repertory (```$git clone https://github.com/TApplencourt/EMSL_Basis_Set_Exchange_Local.git``` for example)
|
|
* That all! You can now, use ```EMSL_api.py```
|
|
|
|
##Usage
|
|
```
|
|
EMSL Api.
|
|
|
|
Usage:
|
|
EMSL_api.py list_basis [--basis=<basis_name>...]
|
|
[--atom=<atom_name>...]
|
|
[--db_path=<db_path>]
|
|
[--average_mo_number]
|
|
EMSL_api.py list_atoms --basis=<basis_name>
|
|
[--db_path=<db_path>]
|
|
EMSL_api.py get_basis_data --basis=<basis_name>
|
|
[--atom=<atom_name>...]
|
|
[--db_path=<db_path>]
|
|
[--with_l]
|
|
[(--save [--path=<path>])]
|
|
EMSL_api.py list_formats
|
|
EMSL_api.py create_db --db_path=<db_path>
|
|
--format=<format>
|
|
[--no-contraction]
|
|
EMSL_api.py (-h | --help)
|
|
EMSL_api.py --version
|
|
|
|
Options:
|
|
-h --help Show this screen.
|
|
--version Show version.
|
|
--no-contraction Basis functions are not contracted
|
|
|
|
<db_path> is the path to the SQLite3 file containing the Basis sets.
|
|
By default is $EMSL_API_ROOT/db/Gausian_uk.db
|
|
|
|
Example of use:
|
|
./EMSL_api.py list_basis --atom Al --atom U
|
|
./EMSL_api.py list_basis --atom S --basis 'cc-pV*' --average_mo_number
|
|
./EMSL_api.py list_atoms --basis ANO-RCC
|
|
./EMSL_api.py get_basis_data --basis 3-21++G*
|
|
```
|
|

##To do
|
|
For now we can only parse `Gamess-us, Gaussian94 and NEWCHEM` (Thanks to @mattbernst for Gaussian94 and NEWCHEM) basis set type file.
|
|
|
|
###I need more format!
|
|
|
|
I realy simple. Just read the few explanation bellow.
|
|
|
|
You just need to provide a function who will split the basis data who containt all the atoms in atom only tuple.
|
|
|
|
Sommething like this:
|
|
```python
|
|
def parse_basis_data_gaussian94(data, name, description, elements, debug=True):
|
|
"""Parse the Gaussian94 basis data raw html to get a nice tuple.
|
|
|
|
The data-pairs item is actually expected to be a 2 item list:
|
|
[symbol, data]
|
|
|
|
e.g. ["Ca", "#BASIS SET..."]
|
|
|
|
N.B.: Currently ignores ECP data!
|
|
|
|
@param data: raw HTML from BSE
|
|
@type data : unicode
|
|
@param name: basis set name
|
|
@type name : str
|
|
@param des: basis set description
|
|
@type des : str
|
|
@param elements: element symbols e.g. ['H', 'C', 'N', 'O', 'Cl']
|
|
@type elements : list
|
|
@return: (name, description, data-pairs)
|
|
@rtype : tuple
|
|
"""
|
|
```
|
|
|
|
Then just add the function in `src.parser_handler.format_dict`. You are ready to go!
