Loading Read Counts
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.
- In
ar_counts
all samples will have read counts for the same set of peak calls. - Some read counts may be 0.
- All peaks in
ar_counts
are 200 bp wide. - All peaks in
ar_counts
are 400 bp wide.
Which of these statements are true?
