8.1 Processing, alignment, quantification
- Processing & alignment see Chapter 7
After Alignment we have a BAM/SAM file which is not human readable:

BAM file
The same information can also be stored in a SAM file:

SAM file
Quantification can be performed already by alignment tools (e.g. STAR), but it can also be performed in R (Rsubread::featureCounts
, QuasR::qCount
, GenomicAlignments::sumarizeOverlaps
)
