When data is loaded into Seurat and the initial object is created, there is some basic metadata asssembled for each of the cells in the count matrix. To take a close look at this metadata, let’s view the data frame stored in the meta.data slot of our merged_seuratobject: There are three columns of information: … Zobacz więcej Now that we have generated the various metrics to assess, we can explore them with visualizations. We will assess various metrics and then decide on which cells are low quality and should be removed from the analysis: 1. … Zobacz więcej After performing the filtering, it’s recommended to look back over the metrics to make sure that your data matches your … Zobacz więcej Based on these QC metrics we would identify any failed samples and move forward with our filtered cells.
