To appreciate this feature, let’s consider an example research design that uses this feature. Suppose that you have scores on a personality test that measures how extraverted or introverted people are, where a lower score indicates that the person is more introverted and the higher, the score, the more extraverted the person is. Now you wish to see if people with higher scores have more fire signs in their chart or perhaps aspects to Jupiter, while the more introverted people have more planets in earth signs and more aspects to Saturn.
You can create an AstroSignature where you assign a negative number of points to astrological influences that you think make the person more introverted and assign a positive number of points to astrological influences that you think make the person more extraverted. You can set Asc in Aries to +15 points and Asc in Sagittarius to +25 points if you think that an Aries Ascendant inclines the person to be extraverted and a Sagittarius Ascendant inclines the person to be very extraverted. You can have as many astrological influences as desired in the AstroSignature. Now you can obtain a correlation of scores on this introversion/extraversion AstroSignature with the scores on the introversion/ extraversion psychology test. Sirius 1.1 can do this correlation test but you must manually enter the test scores for each person. If there are hundreds of individuals that are being analyzed, this can be tedious.
In Sirius 1.2 you can import a file of test scores so that you do not need to manually enter them. This feature was added precisely for the situation described here as being hypothetical, but actually did occur: a researcher had a file of introversion/extraversion personality test scores and this new feature allows the researcher to import those test scores rather than manually enter them.
