Impressions from our Hands-On Session on Napari-KICS.

Chromosome-scale genome assembly is affected by scaffolding errors and may yield incorrect chromosome sizes. Today, we present Napari-KICS, a semi-automated and cost-efficient approach for examining the validity of the assembly by estimating relative chromosome sizes from the respective karyotype images. The method employs threshold-based image segmentation and uses the extracted chromosome areas as proxies for the actual chromosome sizes. The suitability of the approach is confirmed by a strong correlation between area and DNA content evaluated on karyotype images of varied species and achieving a 6 Mb chromosome size error on a reference human karyotype dataset.

Hands-On Demonstrator Series

In the ScaDS.AI Living Lab Hands-On Demonstrator Series, we showcase the latest accomplishments, discoveries, improvements and educational tools of the ScaDS.AI team in the field of AI, Big Data and Data Science. The introductory talk, Q&A and hands-on session will provide you with a chance to familiarize yourself with the demonstrator.
