OMNICYCLES (professional version) allows you to use any aspects that you want, whether traditional, or those based on less common harmonic series. Depending on the aspect file you choose to create a graph, you may employ only the "main" aspects of traditional astrology, or else include others as well. We´ve even included some files which were made to study certain harmonics, and which contain only the aspects related to that harmonic. Among these are files for the quintile, septile and undecile series (harmonics 5,7 and 11). Of course, you may also mix different kinds of aspects in the same file.  You may even define your own aspects, and include them in any file. Here is a list of some of the aspects OMNICYCLES uses: 

Ø Traditional: Conjunction, Opposition, Trine, Square, Sextile, Inconjunct, Quincunx

Ø Other aspects related to the second and third harmonic series: semi- and sesquisquare, novile, binovile, tetranovile,  Harmonic 16 (semi-semisquare and related aspects)

Ø Parallels and antiparallels of declination (though not used by many astrologers, we have seen that these -  especially  the parallel - can be VERY powerful in transit, sometimes every bit as much as the conjunction!)

Ø Several files containing other harmonic series, for purposes of experimentation: 5, 7, 11, 24, 48... and if you´d like, you can add other series as well. OMNICYCLES treats the Descendent and Lower Heaven (IC) as separate points, thereby allowing you to include aspects which are not based on division by 2 (such as the quintile, septile, novile..) to these important points.

All aspects starting with the trine have more than one aspect point; OMNICYCLES lets you differentiate between their "waxing" and "waning" phase. Thus, for the square (for example), you may give different point values to the waxing (90°) and waning (270°) squares. The orbs for each aspect may be defined separately, as well. And... each OMNICYCLES aspect file lets you include up to 25 different aspect tables, so that the various planetary transit>natal combinations may be assigned different point values, according to the aspect.
