EMSL_Basis_Set_Exchange_Local
|
|
=============================
|
|
[](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 (One database for all the basis set of one format);
|
|
* API for scripting;
|
|
* Quick local access without delay;
|
|
* Only need [Python](https://www.python.org/)
|
|
|
|
##Dependency
|
|
* 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 [--atom=<atom_name>...]
|
|
[--db_path=<db_path>]
|
|
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
|
|
```
|
|
##Demonstration
|
|
|
|
|
|
|
|
(For a beter quality see the [Source](https://asciinema.org/api/asciicasts/15380))
|
|
|
|
##To do
|
|
For now we can only parse Gaussian-US basis set type file. (Look at ```./src/EMSL_utility.py#EMSL_dump.basis_data_row_to_array```)
