Gamry DTA

Gamry DTA allows you to read .DTA files generated by Gamry potentiostats. Data is returned as polars dataframes.
Metadata is returned as a dictionary.

Installing

pip install gamrydta

Quick start

import gamrydta

path = ".../some_file.dta"
dta = gamrydta.read()

gamrydta.read(...) returns an instance of an Experiment class, or any derived class such as CyclicVoltammetry.
Main measurement data is exposed as a polars dataframe as dta.data or dta.curves.
Experiment metadata is exposed as a dictionary as dta.header or data.metadata.

Notes

• dta.header/dta.metadata values are strings now. Next release will parse to correct types.
• Gamry-DTA is built on data generated by a Gamry reference 600 potentiostat.
• The author (kristianfkt) do no longer have access to any Gamry potentiostats.

Future releases:

• Parse column name-units according to https://github.com/emmo-repo/domain-electrochemistry
• Parse header fields according to https://github.com/emmo-repo/domain-electrochemistry
• Infer header field types, text, float, etc
• Add retry-cases for encoding errors
• Infer decimal separator if not provided.
• Explorative dashboard.

TODO notes

• Consider swithcing Experiment and derived classe to dataclass.
• A DTAFile class might be convenient to separate Experimet class and file parsing more clearly.
• Header file parsing probaly require different TypedDicts or something for the different kinds. Or dataclass.
