    Fast, accurate and simple analysis of aCGH data

    CytoSure Interpret Software utilises an innovative “Accelerate Workflow” that provides automated data analysis based on predefined settings. This unique feature minimises the need for user intervention and maximises the consistency and speed of the data analysis. The analysis time is further reduced by using a batch processing facility, which allows an unlimited number of samples to be analysed simultaneously using the robust, optimised Circular Binary Segmentation (CBS) algorithm for identifying chromosomal abnormalities (Figure 1). The proprietary SNP calling algorithm and associated thresholds enable accurate calling of regions of LOH (Figure 2). In addition, the bulk load feature allows faster sample loading as multiple sets of sample information can be loaded at once as a text file.

    Analysis can be performed using arrays designed to human genome build 18 (hg18) or 19 (hg19) — with easy, one-click switching between builds. The future-proof database structure allows further new builds to be easily imported and existing data re-mapped.

The gain on chromosome 12 for this chronic lymphocytic leukaemia (CLL) sample contains the zinc finger protein gene ZP384, easily identified in the Cancer gene census genes track.

The green and the bright red rectangles indicate amplifications and deletions respectively. This is the same CLL sample as displayed in Figure 1 and clearly illustrates the gain in the telomere region of the p arm and the region of LOH in p13.31-p12.3.

    Comprehensive data annotation with direct links to external databases and online resources

    CytoSure Interpret Software includes extensive annotation tracks covering syndromes, genes, exons, CNVs and segmental duplication — each of which link to publicly available databases such as ISCA, Decipher, Database of Genomic Variants and the Cancer Gene Census (Figure 3) providing results in context. Which tracks are displayed is fully customisable allowing only tracks of specific interest to be viewed (e.g. cancer-specific tracks) ensuring easy data interpretation. Each track can reference hg18 or hg19 information. Annotations within a track can be coloured allowing easy visualisation. It is also possible to customise what information from the tracks is saved in the report (e.g. how many common variants overlap with an aberration). In addition, CytoSure Interpret Software seamlessly integrates with Cartagenia’s BENCH™ software, allowing users to securely transfer CNV calls for aCGH aberration data management and genotype-phenotype correlation, providing greater confidence in the calls made.

    Robust relational database allowing sophisticated data querying and filtering

    The powerful relational database enables storage of sample data according to its relationship with other data. For example, samples can be segregated into different projects by sample type or by user, thereby simplifying analysis as only the data relevant to your work is visible. Annotation of individual samples is defined by the user; custom fields enable information applicable to your samples and experimental set-up to be stored within the database. The information contained within these custom fields can then be added to the final report. The database can be accessed simultaneously by multiple users.

    Back-ups of the database are straightforward; simply choose a full, partial or mini back up, creating a compressed file which can be reinstated if necessary using the restore function. The installation of the relational database is customisable with a choice of database management systems designed to integrate with your current IT infrastructure.

    The relational database allows flexible data searching utilising “Quick” or “Advanced” search functionality. Advanced search uses Boolean operators to query sample and experimental details as well as aberrations that are stored in the database. The search criteria can be saved allowing searches to be easily repeated.

    CytoSure Interpret Software also makes it easy to examine inheritance patterns within related samples using a unique “Family Tree” viewer. Probands can be linked to parents and other family members with the facility to view three generations together (Figure 4).

    Extensive customisation options to meet the needs of your laboratory

    CytoSure Interpret Software gives you the flexibility to optimise data analysis settings for your laboratory's specific needs as well as the freedom to customise data reports to show only the information you need. In addition, the permission-based log-on structure enables greater flexibility with respect to management of user accounts. Within an organisation an Administrator can control the access and functionality available to users. This ensures consistency of analysis and reporting and provides an audit trail of any changes made within the software.

    “I recently integrated the new CytoSure Interpret Software into my laboratory workflow. I have been extremely impressed with the ease-of-use and flexibility of the software. In our experience, OGT is very responsive to customer feedback and they have already implemented several of our suggested improvements. OGT has indeed produced an excellent software package that should become a useful tool for cytogeneticists and molecular geneticists.“

    Fully integrated, automatic analysis of array image files

    CytoSure Interpret Software can be used with the CytoSure Interpret Feature Extraction Module to analyse TIFF images from a variety of commonly available microarray scanners, including NimbleGen, Agilent, Innopsys and Axon. The module comes pre-loaded with template files enabling images to be feature extracted and seamlessly loaded into the Accelerate Workflow without the need for user intervention. The CytoSure Interpret Feature Extraction Module will also automatically search for TIFF images as they are generated, making it possible to start scanning, walk away and return to fully analysed data — a perfect fit to scanning at the end of the working day and interpreting results the following morning. 

    Alerts can be set to ensure that only good quality images are analysed, informing the user of any images that may need to be visually inspected. As well as streamlining the analysis workflow and reducing hands-on time loading and transferring data, the CytoSure Interpret Feature Extraction Module is agnostic regarding the source of TIFF images. It is also possible to scan a high-resolution microarray with a small feature size (i.e. 30 μm) at a low resolution (5 μm), widening the array choice for users with 5 μm scanners.

    Constant innovation ensuring class-leading data interpretation

    Constant innovation ensures that CytoSure Interpret Software remains the industry-leading aCGH analysis software. Our dedicated software development team are continually implementing enhanced features and capabilities in response to new product development and customer feedback.To complement our range of arrays containing both CNV and SNP probes, CytoSure Interpret Software can identify DNA regions exhibiting loss of heterozygosity (LOH), whole chromosome uniparental disomy (UPD) and segmental UPD. In addition, potential mosaicism can now be detected using our specialised threshold factors. Another unique feature is the facility to identify sample mix-up when used in conjunction with CytoSure ISCA Sample Tracking Spike-ins — providing confidence in results. This constant innovation ensures you can rely on CytoSure Interpret Software to provide fast and reliable delivery of meaningful results.
