Sample Topography from Grid

Use the IPTOPOGRID GX to import from a grid file the topography information for all the electrodes in the current database.

Import Topography from a Grid file dialog options

Topography grid file

The file to extract the topography (Z component) from. Script Parameter: IP.TOPOGRID

Application Notes

The input grid is linearly interpolated to obtain the grid value at each set of XY coordinates in the database. If the XY point falls outside the grid, the returned value is a dummy.

In order to maintain the syntax of the electrode location channel names, if the Z channel(s) are previously present in the database they are silently overwritten.
