VAFT is developed and maintained by the VEST team at Seoul National University. This is the canonical route for human support: public data access, privileged writes, library maintenance, and VEST technical-system enquiries.

Reading the VEST database

Read access is public. You do not need to negotiate credentials with anyone — the shot database ships with a read-only account. Install the HSDS client, then run hsconfigure (a console script provided by h5pyd, which writes ~/.hscfg):

python -m pip install --no-deps h5pyd==0.20.0
hsconfigure

Answer the prompts with the public reader account:

Server endpoint []: http://147.46.36.244:5101
Username []: reader
Password []: test
API Key [None]:
Testing connection...
connection ok

Confirm from Python:

import vaft

vaft.database.is_connect()      # -> True
ods = vaft.database.load(39915)

The full procedure, including environment setup, is in the Quick start guide and Installation guides.

Database write access and data policy

Saving to the shared database — uploading shots, writing into a directory of your own — is restricted to authorized users. To request write credentials, contact:

peppertonic18@snu.ac.kr

Please say who you are, which institution you are with, and what you intend to write. Until write access is granted you can still run the entire analysis chain locally: load a shot with the reader account (or use the sample data packaged in vaft.data), process it, and save the result to a local file.

VAFT maintenance, bugs, and features

For a library-maintenance question, contact satelite2517@snu.ac.kr. File bugs, feature requests, and patches on the issue tracker — that way the discussion stays with the code:

github.com/VEST-Tokamak/vaft/issues

A useful report states the VAFT commit or version, your Python version, the shot number (if the problem is data-dependent), the call you made, and the full traceback. Pull requests are welcome on the same repository.

Diagnostic and heating-system enquiries

The VEST diagnostics and data availability page names the manager recorded for each diagnostic, control, or heating/current-drive system. Individual technical email addresses are not published there. Email the VAFT maintainer for routing, naming the system and shot number where applicable.

The lab

VAFT comes out of the Nuplex laboratory at Seoul National University, which operates the VEST spherical torus. For the device, the research programme, and the people behind it:

Background on the framework itself, including how to cite it, is on the About page.
