kayras

Karyotyping toolkit

From micrograph to ISCN — and back again.

KAYRA does the arranging so your cytogeneticists spend their time reading, not sorting. The same models train new analysts — and generate unlimited, ISCN-accurate practice cases, including the rare rearrangements a lab may see once a decade.

The tools

Analysis

KAYRA

Segmentation and classification of metaphase micrographs, with karyogram assembly, sample records and an ISCN suggestion in one workspace. The cytogeneticist reviews and decides; the system does the counting.

Training

Classroom

Practice telling chromosome types apart. Pick the types you want to drill and how many questions to answer; each test is drawn from a real micrograph and marked question by question.

Synthesis

DDG

Chromosome images generated from an ISCN code — faithful to the requested type and rearrangement, yet different every time. From a single chromosome to a full metaphase spread, for training and validation.
