The error message on lines 97-100 shows that PyLith is looking for `final_slip_opening` in the spatial database, but it found `final-slip-opening` instead. We need to change the dashes (used in PyLith v1.x and v2.x) to underscores (used in PyLith v3.x); we made this change to be consistent with the names of the output fields. ## Resolution ```{code-block} cfg --- caption: Correct error in `fault_slip.spatialdb`. --- # Error value-names = final-slip-left-lateral final-slip-opening initiation-time # Correct value-names = final_slip_left_lateral final_slip_opening initiation_time ```
