Copy MSn data in an xcmsRaw to the MS slots
Description
The MS2 and MSn data is stored in separate slots,
and can not directly be used by e.g. findPeaks().
msn2xcmsRaw() will copy the MSn spectra
into the "normal" xcmsRaw slots.
Usage
msn2xcmsRaw(xmsn)
Arguments
xmsn
an object of class xcmsRaw that contains
spectra read with includeMSn=TRUE
Details
The default gap value is determined from the 90th percentile of
the pair-wise differences between adjacent mass values.
Value
An xcmsRaw object

xr <- msn2xcmsRaw(xrmsn)
p <- findPeaks(xr, method="centWave")
