I would expect that r.out.gdal can take care of that. > Sometimes it exports different headers that are not compatible with NetLogo > raster ingest.

This happens in case of non-square pixels: http://www.gdal.org/frmt_various.html "If pixels being written are not square (the width and height of a pixel in georeferenced units differ) then DX and DY parameters will be output instead of CELLSIZE." So you may control that with g.region prior to r.out.gdal.
