imas2xarray

Imas2xarray is a library that makes it as simple and intuitive as possible to read and write IMAS data in HDF5 format with Python. There is no need to manually define the paths or fiddle with the different dimensions and long keys.

Reading

>>> from imas2xarray import to_xarray
>>>
>>> path = '/pfs/work/g2aho/public/imasdb/test/3/92436/1/'
>>> ids = 'equilibrium'
>>>
>>> ds = to_xarray(path, ids)
>>> ds
<xarray.Dataset>
Dimensions:         (time: 1, rho_tor_norm: 101, ion: 4)
Coordinates:
  * time            (time) float64 50.04
  * rho_tor_norm    (rho_tor_norm) float64 0.0 0.01 0.02 0.03 ... 0.98 0.99 1.0
Dimensions without coordinates: ion
Data variables: (12/14)
    q               (time, rho_tor_norm) float64 0.7887 0.7888 ... 4.262 4.845
    collisionality  (time, rho_tor_norm) float64 23.23 7.554 ... 7.31 10.19
    t_i_ave         (time, rho_tor_norm) float64 1.036e+04 1.036e+04 ... 508.4
    ...              ...
    n_e             (time, rho_tor_norm) float64 7.976e+19 ... 1.742e+19
    p_i             (time, ion, rho_tor_norm) float64 1.242e+05 ... 0.2948
    n_e_tot         (time, rho_tor_norm) float64 7.976e+19 ... 1.742e+19

Writing

>>> from imas2xarray import to_imas
>>>
>>> ds['t_e'] *= 1.1
>>>
>>> to_imas(
>>>     path,
>>>     dataset=ds,
>>>     ids=ids
>>> )
