There is a program in GMT called grdraster that reads raster files (uncompressed) and extracts
a window of the raster file and writes it in grd format. You have to prepare
a grdraster.info ascii file with the descripion of the raster files you want to operate on.
The source and README are in ..../gmt/src/dbase.
For the reverse process what I do is, get rid of the header file with the tail +c1469 unix command
and then prepare a header file with the info provided with grdinfo gmt command.
I know it could be automated, but for the moment is the way I do it.
Hope it helps
