Earlier this month, we launched NanoString Masterclass Series, designed to enhance scientific understanding and practical skills in advanced nCounter data analysis. Dr. Ryan Friese (VP of Rosalind Customer Experience) hosts the series to share his best practices from years of working hands-on with scientists in BioPharma and Academia as a Field Application Scientist for NanoString.

Importance of Custom Pruning
Custom pruning of low expressors is crucial in genomic research, as it helps to significantly reduce background noise, thereby enhancing the overall clarity of the data. This selective removal focuses analysis on genes with higher expression levels, which prevents the potential biases caused by random fluctuations in genes with low expression.
The Rosalind platform simplifies this essential step by employing advanced algorithms designed to intelligently identify and eliminate these low expressors. This automation not only streamlines the research workflow but also substantially improves the quality of the data.
Key benefits of pruning low expressors include:
- Enhanced Data Clarity: By filtering out statistical noise, the genuine signals from highly expressed genes are more discernible, making the data cleaner and clearer.
- Improved Analysis Accuracy: With less clutter in the dataset, analytical algorithms can model gene expression relationships more accurately, leading to more accurate results.
- Increased Computational Efficiency: Reducing the number of data points to process can significantly speed up computational tasks, allowing for faster iterative analysis, which is vital in high-throughput environments.
Algorithms in Custom Pruning (downloadable Resources)
During the webinar, Ryan demystified the complex algorithms and calculations integral to the custom pruning process. For those interested in a deeper dive, we have made the relevant resource files available for download. These materials will allow you to closely follow the methodologies discussed and apply the concepts alongside the webinar replay.
Why Rosalind Enhances Pruning Efficiency
The Rosalind Advanced NanoString Data Analysis module enhances the pruning of low-expression probes by utilizing sophisticated algorithms combined with a user-friendly interface:
-
Intelligent Pruning: Automatically applies best-practice methods and advises on optimal thresholds for pruning, tailored specifically to each dataset and research objective.
