For images the situation is a little better because there exists a standard in the astronomical community: the FITS format (see also fits(5NEMO)). ccdfits convert a NEMO image to standard FITS diskfile, which can be read and manipulated by various image processing packages. The reverse program, fitsccd, is also available, and can convert most FITS images into NEMO's image(5NEMO) format. When importing FITS images into NEMO, always be concerned with the units, since NEMO insists that the origin be at (0,0,0).
