Chromosome Analysis Suite 4.3 (ChAS 4.3)
- Improve mosaic segmentation in both detection as well as breakpoint accuracy
- Co-visualize NGS and microarray data together
- Access supporting evidence for segment prioritization. Add custom annotations prior to uploading into your personal ChAS database for reference in future sample investigation.
- Choose between two prioritization methods to suit your individual needs
- Load samples from ChAS into the Multi-Sample Viewer (MSV) to visualize cohorts of samples simultaneously. Install the MSV as part of the Reproductive Health Analysis Software.
- Display database contents in a histogram track
- Expand your reporting options with the ability to export to Microsoft Word files, create paragraph-style segment tables, generate automatic report file names, and use a quick export button for all graphs and tables
CytoScan Automated Interpretation and Reporting (AIR) Solution
Streamline genetic data analysis to increase productivity with consistent interpretation and reporting
Franklin by Genoox is an end-to-end research solution for the analysis of genetic data with advanced AI-driven interpretation.

Additional software files and sample data sets
Analysis files
ChAS requires sets of analysis files to create and visualize copy number, LOH, and genotyping data files for CytoScan Cytogenetics Suite, OncoScan CNV Plus Assay, and OncoScan CNV Assay arrays.
To download these files into the appropriate ChAS library folder from within the software, use the Help>Update Library and Annotation Files functionality or download them from the Analysis Workflow using Utilities>Download Library Files. Within RHAS you can download them from Preferences>Download Library Files.
Alternatively, to copy the files into your ChAS Library folder manually, download the Analysis Files.zip to the data analysis workstation, extract the zip archive, open the folder containing the files, copy all of the files, and paste them into the ChAS Library, using the instructions in the ChAS User Guide located in the ChAS software zip package.
