As you have seen in the video, you have to create a set of consensus peak calls before you can test for differential binding. This can be achieved with the following line of R code:
ar_counts <- dba.count(ar_peaks, summits=200)
Consider the following statements.
ar_counts
all samples will have read counts the same set of peak calls.ar_counts
are 200 bp wide.ar_counts
are 400 bp wide.Which of these statements are true?
