Identifiers not being parsed through evaluator #553
Comments
|
I can reproduce this; there must be something different about this dataset that causes the parsing to fail in ways that the other supported properties do not. Or maybe it's not correctly being loaded as a plugin |

Whatever's going wrong is surfacing from here: It can't be that all identifiers are missed, otherwise it wouldn't think everything was pure water Here's the script I'm using to test, based on what you shared: from openff.units import unit
from openff.evaluator.datasets import PhysicalProperty, PropertyPhase
from openff.evaluator.datasets.thermoml import thermoml_property
from openff.evaluator.datasets.thermoml.thermoml import ThermoMLDataSet
from openff.evaluator.plugins import register_default_plugins, register_external_plugins
@thermoml_property(
"Osmotic coefficient",
supported_phases=PropertyPhase.Liquid | PropertyPhase.Gas,
)
class OsmoticCoefficient(PhysicalProperty):
def default_unit(cls):
return unit.dimensionless
register_default_plugins()
register_external_plugins()
ThermoMLDataSet._from_url(
"https://trc.nist.gov/ThermoML/10.1016/j.fluid.2006.09.025.xml"
) |

I traced this ultimately back to an incorrect calculation of MW, meaning that the non-O compound gets dropped at the lines below due to an apparent mole fraction around 1e-27. Raising #569 to fix. openff-evaluator/openff/evaluator/datasets/thermoml/thermoml.py Lines 1398 to 1408 in c8c476a |

With the current development head (which would land in 0.4.10, most likely) including @lilyminium's recent fix, I think this is doing what one would expect? I blindly copied my code snippet from earlier In [26]: df = ds.to_pandas()
In [27]: df.describe()

Describe the bug
I'm trying to use evaluator to filter papers with Osmotic Coefficient values from ThermoML. I've succesfully created the property type, filtered out dois with osmotic coefficients, converted them to a pandas dataframe, and printed the dataframe into a csv file. However, evaluator is not recognizing or reading all of the substances involved from the papers. It only recognizes one component, even if the thermoml .xml data does report other identifiers (StandardInChI, CommonName).
To Reproduce
Register Custom ThermoML Property:
Load ThermoML Data Set:
ds = ThermoMLDataSet.from_doi('10.1016/j.fluid.2006.09.025')Write to csv:
Check involved compounds:
ds.substancesIf the problem involves a specific molecule or file, please upload that as well. -->
filt_ds_osmcoeff.csv
Output
command "ds.substances" outputs "{<Substance O{solv}{x=1.000000}>}"
Here is link to the ThermoML report of this specific example paper proving there are more: https://trc.nist.gov/ThermoML/10.1016/j.fluid.2006.09.025.html
Computing environment (please complete the following information):
conda list:Additional context
I believe the problem is that the classmethod "from_xml_node" in the thermoml.py is not correctly identifying the xml identifiers so it cannot convert StandardInChI to smiles, for example.
