Over expression among all cells is indicative of housekeeping features, while dimly expressing genes will contribute noise to downstream clustering. Quality Control for mixed omics data will work much the same as with other data sets in terms of cells – consisting of the removal of outlier events which might consist of doublet events or empty reads:įor genes also, filtering outliers is recommended. Once you’ve established a proper Cell ID in both data matrices, you can simply drag and drop the Flow data file right on top of the sequencing matrix in SeqGeq’s workspace to merge the two. The one hitch here, your Flow data will need to contain a Cell ID column, which matches precisely the Cell ID column in your single-cell sequencing data file – Something to consider careful ahead of time when designing an experiment combining Flow and scRNA-Seq techniques: Such data can be easily merged with your expression matrix from single cell sequencing (or potentially from bulk sequencing as well). In this case cells are named by their plate and WellIDs. The Index Sorting plugin for FlowJo can be used to export fluorescence intensity values from each well in an index sorted FCS file, in CSV format. This raw data is also available on the Immport data sharing site under study code: SDY997 This data was generously provided by the Advancing Medicines Partnership (AMP) group. Most of the data illustrated in this workflow is available as one demo data file which is already combined. SeqGeq gives users the ability to very easily combine both fluorescence intensity information per flow channel, per cell (or per sample in the case of bulk sequencing) with their expression matrix from sequencing. In these cases, many researchers don’t realize they’ve already gathered a powerful dataset which can be used to compliment the sequencing analysis. Combining Flow and Single Cell SequencingĬertain sequencing methods will utilize index sorting from flow cytometry as an upstream step in sample preparation.
