To find out if they do repeat we group the peaks by their m/z value, rounded to a given decimal place, then we count how many peaks have the same rounded m/z value. This way we can discard the groups below a certain threshold.

|
We should note that some groups below the threshold can still be kept,
|
|
|
|
if they are adjacent to a group that is above the threshold, this is done to avoid discarding groups that may have been split by the rounding value.
