data |
A data frame containing SWATH data. |
mscore |
Value that defines the mscore threshold according to which the data will be filtered. |
percentage |
Percentage in which replicas the transition has to reach the mscore threshold. |
rm.decoy |
Option to remove the decoys during filtering. |
mscore.col |
Defines the column from which to retrieve the m_score. If you use JPP (Rosenberger, Bludau et al. 2017) this can be used to select between Protein and transition_group m_score. |
Returns a data frame with the filtered data.
