in Oasis montaj
Hi,
I'm struggling to perform grid operations in Oasis Montaj (initial pre-process ahead of FFT using MAGMAP). My grid is about 100k x 80k cells. I get an error suggesting the largest allowable grid dimension is 65536 (2^16). Does anyone know if there's a way to change the maximum size in Oasis Montaj?
Cheers

    I wonder if you can work around the limit with the Geosoft GX API?

    Hi @NickWilliams the 2^16 value is currently a hard limit on FFTs in Oasis montaj. As a workaround, we recommend that you break up the area into tiles.

    FYI: In OM 9.9 the hard limit on the grid size that Magmap can handle has been lifted.
