Once raw read data have been obtained, the expression level of genomic features such as transcripts or genes must be quantified.
This wording is a bit jolting as it implies some continuity from the previous section, which is not the case. Better to break the flow and say something like:
An important initial step in scRNA-seq data processing is to quantify the expression level of genomic features such as transcripts or genes from the raw sequencing data.
... can be readily used in a scater workflow (Figure 1).
Put a bit of a link to the previous section and say something like:
... can be readily stored in a SCESet object and used in a scater workflow (Figure 1).
