35 This tool will create a visualization of the bed file that is selected.
36
37 **Parameters**
38
39 - **Shift at 5' end** should be used when the location of interest is at a fixed distance from
40 the 5' end for **all sequenced fragments**!
41
42 For example if the sequenced sample consists
43 mono-nucleosomal DNA (146bp) we should expect that
44 each nucleosome midpoint is located at 73 bp from the 5' end of the fragment.
45 Therefore we would enter 73 as the shift parameter. Once corrected the reads
46 on each strand will coincide and indicate the actual midpoints
47 of the nucleosomes.
48
49 When shifting the averaging process in GeneTrack is able correct for longer or shorter
50 than expected fragment sizes as long as the errors are reasonably random.
