I have been trying to warp ECW and Ozfx3 map formats to GeoTiff format. I have navigated to Raster>Projections>Warp(reproject) I have then selected the file to warp the output that I want and the process starts but each time the process fails within 5 seconds with the dialogue "The process crashed some time after starting successfully". So far I have had no success could someone assist me please. Regards Bart.

What tool are you using to attempt to warp the rasters? – DavidF Nov 16 '12 at 5:18
have you tried using gdalwarp from the shell? – dmci Nov 16 '12 at 11:20

Warping is generally done to change coordinate systems or re-sample an image, so I'm not sure if warping is the correct function you are seeking.

If your intention is to convert an ECW file to a Tiff then I think you should be able to use the gdal_translate utility, with a command like:

gdal_translate -of GTIFF "input.ecw" "output.tif"
