I’m trying to generate stage poles for the South Atlantic using rotconverter. Below is my code:
gmt rotconverter SAM-AFR -Fs > stage_poles.txt
Then I rotate the isochrons from the South American plate (triangles) and African plate (circles) using the above stage poles. Only the isochrons with total poles meet when rotated back to that chron (left image). All other isochrons between total poles have gaps when rotated back are not closing (right image).
I can upload data files if needed.
Thanks for any help!!
