Computer-aided analysis of chromosomal aberrations occurring in an abnormal human karyotype.

A semi-automatic method for recognition of chromosomal changes is presented: from a coded description of an abnormal chromosome (formulated with the aid of an R-banding technique), a computer program makes simulations to reconstitute this chromosomal image from a group of normal chromosomes. Nine types of aberrations (see text) can thus be recognized and the aggregate structure of a group of abnormal chromosomes occurring in a human karyotype can also be rediscovered.
