filter_on_max_peptides {SWATH2stats} | R Documentation |
In order to reduce the data, the data is filtered only for the proteins with the highest intensity peptides.
filter_on_max_peptides(data, n_peptides, rm.decoy = TRUE)
data |
A data frame containing SWATH data with the column names: ProteinNames, PeptideSequence, PrecursorCharge, Intensity. |
n_peptides |
Maximum number of highest intense peptides to filter the data on. |
rm.decoy |
Option to remove the decoys during filtering. |
Returns a data frame of the filtered data
