HyperFinder is freely available as a FlowJoTM version 10 plugin and its results can be further analysed in FlowJo or easily sent to BD FACSDivaTM. HyperFinder helps investigators to obtain training sets for populations using the most appropriate analytical methods, and automatically create optimized gate sequences to identify and sort desired populations. To address these issues, we have developed HyperFinder, a novel method that greatly improves insights into the data and enables the ability to efficiently enrich and sort any populations of interest. The challenges deepen if phenotypes are classified by clustering, or identified by machine learning or dimensionality reduction techniques such as t-SNE or UMAP.
Facs flowjo manual#
While helpful to explore underlying biology, manual gating– often based on subjective combinations of one- or two-dimensional gates– may not efficiently capture all phenotypes to be sorted. But traditional workflows for analysing and sorting complex cell populations can limit discovery by creating speed, labor and reproducibility bottlenecks. To learn more about performing SPICE analyses and to get access to all of our advanced materials including 20 training videos, presentations, workbooks, and private group membership, get on Mastery Class wait list.Flow cytometry advances like high-parameter sorters and computational analysis are increasingly critical to basic and clinical research. This is a very simple case, in fact so simple SPICE is not really needed, but it is a good example of where to begin with SPICE, starting from data you already have with minimal manipulation. It has seen dramatic advances over the last 30 years, allowing unprecedented detail in studies of the immune system and other areas of cell biology. Use SPICE’s commands on the left to show averages by patient, or overlay comparison of smokers vs non-smokers, or whatever question fits your work. Flow cytometry is a powerful tool that has applications in immunology, molecular biology, bacteriology, virology, cancer biology and infectious disease monitoring. Read the help file for details on formatting data. Be careful with formatting, as SPICE is pretty particular about that.

Paste your tabular data into Excel, or really any software that can save your data as a comma separated value file (CSV). Don’t forget to include Keywords! In my case, I would add on a keyword about whether a sample came from a smoker or non-smoker, as well as an identifier.Ĥ. In this simple example you have made 2 gates for CD309+ and AC133+. Use Boolean gates to define all possible subsets. If you are interested in percentage of CD34+ cells that also express AC133 and/or CD309, create gates for your CD34+ population, and individual gates for the dependents. Gate down to your base population of interest. At the individual level, that’s easy and what standard data analysis packages can do.ġ. Take, for example, research interested in CD34+ cell counts. SPICE is an acronym for Simplified Presentation of Incredibly Complex Evaluations, and it is designed to look at these complex multidimensional data sets. You can read the paper about the design and math behind SPICE here. SPICE was developed in order to make sense of the increasingly complex data sets that modern flow cytometric methods can produce. To overcome this limitation, and to allow for better discovery science, Mario Roederer and his colleagues have developed a solution. With data complexity of this nature, one can export the numerical data to a third party analysis package, but even then the analysis can be difficult to perform. What do you do when you have a large dataset, with multiple sampling conditions, and multiple outcome measurements? Even beginners are starting with 5+ color assays, and the adoption of mass cytometry has the potential to increase our headaches even more.Ĭurrent data analysis methods are good for single tubes or small cohort studies. Gone is the rule of 2-3 color experiments. Flow cytometry data analysis is getting more complex.
