Save the grid

Save the Grid -- Select the "SeaGrid/SaveAs..." menu item, then enter a filename for saving the current grid as a "SeaGrid" file. The "SeaGrid" file itself can be converted to SCRUM or ECOM format, using the standalone M-files named "seagrid2scrum" and "seagrid2ecom", respectively.

Continue Playing -- Change something about the grid.

Revert to saved grid

Revert to Saved Grid -- Select the "SeaGrid/Revert To Saved" menu item. SeaGrid will use those data to revert to the state of the grid at the time the most recent file was saved. To choose another saved grid besides the most recent one, select "SeaGrid/Load/SeaGrid File..." and interact with the ensuing dialog.

Land Masking

Land Masking -- Select the "Compute/Land Mask" menu item to have SeaGrid mask the cells whose centers it determines to lie on the land, as defined by the coastline. Go to the next step to see the mask. (Since updating the mask can be slow, users may wish to toggle it off when not needed.)

Masking tool

Masking Tool -- Select the "Compute/Masking Tool" to make the individual grid cells interactive. They can be toggled by clicking with mouse button #1. While the tool is active, the grid may not be reshaped. The masking tool can be hidden by re-selecting the same menu item.

Erase land mask

Erase Land Mask -- The land mask can be reset by selecting "Compute/Erase Mask". Do so, then hide the masking tool.
