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_countsall samples will have read counts for the same set of peak calls.
ar_countsare 200 bp wide.
ar_countsare 400 bp wide.
Which of these statements are true?
