Hi Steven,
               the ige files are ERDAS imagine overflow files. There should
be a standard img file there too, so if you have a file some_image.ige
there should be another file some_image.img which belongs with it. gdal
(and thus presumably raster) can handle this file by just using the
some_image.img as the input filename. It should sort the some_image.ige
part out itself. A word of warning, the ige files are for the images which
are too large for the standard HFA format (I think larger than 2gig). HFA
doesn't compress these overflow files, so they can get quite large. GeoTIFF
doesn't have this problem, but you might have to look at the creation
options, particularly for BIGTIFF.
