filter_low_information_fragments.Rd
Filter to high information fragments based on one of several filter_methods
filter_low_information_fragments(
grouped_ms2_data,
filter_method = "top5union",
signal_fraction_co = 0.001
)
output of extract_and_group_fragments
method for filtering low-information fragments:
the union of the 5 most abundant fragments (w/ intensity >1% of total signal)
take fragments which are present in more than 10 spectra or >= 20% of spectra or that are the most abundant ion of any spectra.
take fragments which represents more than signal_fraction_co
fraction of the total signal across all peak spectra.
fraction of total signal that a fragment must represent to be retained when using "signal_pool".
grouped_ms2_data with low-information fragments removed.
