To convert the finite rotations in the file model_finite.APM to stage poles, run
**rotconverter** model_finite.APM **-Ffs** > model_stages.APM

To obtain Nazca motion relative to Pacific hotspots by adding the motion
of Nazca relative to a fixed Pacific to the Pacific-Hotspot reference model DC85_stages.d,
and report the result as finite reconstruction poles in the northern hemisphere, try

**rotconverter** DC85_stages.APM + Pac_Naz_stages.RPM **-N** **-Fsf** > Naz_HS_finite.APM

To add the final rotations ROT(150.1, 70.5, -20.3) and ROT (145.0, 40.0, 11.4), try

**rotconverter** 150.1/70.5/-20.3 + 145/40/11.4

which prints out 157.32, -80.44, 11.97.

To make stage rotations suitable for generating flowlines (fracture zones) from a model
of relative plate motions PL1-PL2.RPM, assuming symmetric spreading,, try

**rotconverter** PL1-PL2.RPM **-E** **-Ffs** > PL1-PL2_half.RPM

**rotconverter** - PL1-PL2.RPM **-E** **-Ffs** > PL2-PL1_half.RPM
