Hi Mathis,

Unfortunately the raster must represent _present day_ data (in order to be reconstructed by GPlates).

Have a look at this [post](https://discourse.gplates.org/t/assigning-plate-id-to-non-present-day-raster/766/2) for more detail, and links to reconstructing a raster representing data at a **non-zero** time using [GPlately](https://github.com/GPlates/gplately).
