Its manager classes ( ERTManager , SRTManager ) handle the full workflow from data loading to inversion to visualization in a few lines. Avoid pyGIMLi when : You need methods beyond near-surface (use SimPEG), or you require a commercial-grade reporting pipeline. Common Workflows ERT data inversion and visualization Load ERT data file with ert.load(\"survey.ohm\") Inspect data: check measurement count with data.size() , plot pseudosection Remove outliers or bad data points Create ERTManager with data Run inversion: mgr.invert(lam=20) (start with higher lambda) Check chi-squared value (target ~ 1) Visualize result with mgr.showResult() Export mesh and model to VTK for ParaView: mgr.mesh.exportVTK() Adjust lambda and zWeight if needed, re-invert Inversion Tips Start with higher lambda (50-100) and decrease Check data quality - remove outliers before inversion Use zWeight < 1 for layered structures Check coverage - low coverage = poorly resolved Chi-squared ~ 1 indicates good fit without overfitting References Geophysical Methods - Supported methods and workflows Mesh Generation - Mesh creation and quality control Scripts scripts/ert_inversion.py - Complete ERT inversion workflow",
