I have a software that can read NASA JPL DE406 ephemerides files, but the program returns the coordinates of any given planet in x,y & z. Can someone please tell me how to convert them to zodiac coordinates, e.g; Libra 03 45' 53"? Many thanks!

X, y, and z? I never heard of that. The system of right ascension and declination should be applicable to anything, astrological or astronomical. In your Libra example, you have given a right ascension, only Libra is around 15h. All it would need is a declination for you to pinpoint it. I think you should use a different database. Nearly all sources use RA and dec.

Not sure about x,y,z coordinates, but if you can get positions in equatorial RA/Dec, this site has the equations to do the conversion to ecliptic coordinates: http://www.pietro.org/Astro_Util_StaticDemo/FDetailEclEquatCoord.htm
You'll have to do a further conversion of longitudinal degrees to sign-degree coordinates, using 0° longitude as 0° Aries.
You may also need to watch your equinox dates - is the ephemeris giving you true equinox or 2000.0?

You basically don't need to, since astrology is a load of **** so don't waste your time. :)
