In qzhang503/proteoQ: Processing and Informatic Analysis of Mass Spectrometrirc Data

Add retention time apex for a chunk of PSMs under a single RAW

Description

For parallel processing.

Usage

addApexes(
  rts,
  mzs,
  trs,
  gap_bf = 250L,
  gap_af = 250L,
  max_rt_delta = 240,
  step = 1e-05,
  yco = 100,
  min_y = 2e+06
)

Arguments

rts	A vector of retention times at MS2 events (pep_ret_range).
mzs	A vector of m-over-z values for PSMs.
trs	MS1 trace data.
gap_bf	A leading gap of maximum allowance in retention times between an MS2 scan and a peak apex.
gap_af	A following gap of maximum allowance in retention times between an MS2 scan and a peak apex.
max_rt_delta	The maximum allowance in retention-time difference between the identifying MS2 event and apex.
step	A step size in mass for mass error tolerance.
yco	The cut-off in intensities.
min_y	The minimum peak area.
