While detecting peaks it becomes evident that some peaks should not be considered for further
comparison because they are out of range (not within the size standard fragments) or they are
false peaks (e.g. too low).
Peak filtering excludes certain peaks from the final set of peaks by setting filter criteria. For
example it can be a good idea to exclude peaks that do not have a minimum height, area or
height-to-width ratio. If peaks have a base size smaller than the smallest size standard fragment
or higher than the highest size standard fragment, these peaks should be filtered out because
they cannot be sized exactly.
