Rotating flowlines with gplately

[peterH105]

Dear GPlates community,

I want to link rotated flowlines together with an age grid back in time using gplately. Currently, the underlying grid is rotated back correctly, while the flowlines are not moving (see attached left plot, rotated back to 60 Ma). Presumably, because the plot of the flowlines is not linked to the plate rotation model. I tried with model.reconstruct, but I did not succeed.

My question is: How to link the flowlines to the underlying plate motion model? My input is similar like shown in Example 09 (lef_lon, left_lat, right_lon, right_lat, model). In GPlates this exercise works well, when constructing the flowlines(see right plot).

Thanks for considering my request, hope you can help!

Cheers,

Peter

It looks like the flowlines are always at present day (in GPlately) – judging by this line of code (which appears to always reconstruct to present day).

@GPlates/gplately-dev: Should we add a reconstruction_time parameter to PlateReconstruction.create_flowline? Currently it's hardwired to 0 Ma. Here is a flowline example in pyGPlates - only real difference is the reconstruction time. Same applies to PlateReconstruction.create_motion_path.
