Clip in what regard?

You can use gdal_translate to pull out a subarea of a MrSID image.


gdal_translate -srcwin 0 0 1000 1000 in.sid out.tif

That would take the top left 1000x1000 chunk.

Or you can use the -projwin parameter to pick a region in georeferenced
coordinates.  There is also a gdal_rasterize command that can be used to
mask stuff based on a polygon but that is more involved.
