findBandsFIA: Detect band in a FIA acquisition
In proFIA: Preprocessing of FIA-HRMS data

Description Usage Arguments Value Examples

Detect bands of points with similar mass in conscutive scans. Points may be moved if a better candidates is found.

findBandsFIA(
  xraw,
  firstScan = 1,
  lastScan = length(xraw@scantime),
  ppm = 2,
  sizeMin = NULL,
  dmz = 5e-04,
  beginning = NULL,
  end = NULL,
  nIso = 3,
  fracMin = 0.6
)

`xraw`	An xcmsRaw object as returned by `xcmsRaw`.
`firstScan`	The first scan to be considered, 1 for general use.
`lastScan`	The last scan to be considered.
`ppm`	The mass deviation in ppm for point in consecutives scans.
`sizeMin`	The minimum size of a band.
`dmz`	The minimum mass tolerance,useful for small masses
`beginning`	The scan of the injection. May be determined using `determiningInjectionZone`.
`end`	The end of injection, may be estimated using `determiningInjectionZone`.
`nIso`	The minimum number of consecutive points for a signal to be detected.
`fracMin`	The minimum fraction of points necessary in beginning:end for a signal to be detected. contaminated by solvent.
