xcmsRaw {xcms} | R Documentation |
This function handles the task of reading a NetCDF/mzXML file containing
LC/MS or GC/MS data into a new xcmsRaw
object. It also
transforms the data into profile (maxrix) mode for efficient
plotting and data exploration.
xcmsRaw(filename, profstep = 1, profmethod = "intlin", profparam = list())
filename |
path name of the NetCDF or mzXML file to read |
profstep |
step size (in m/z) to use for profile generation |
profmethod |
method to use for profile generation |
profparam |
extra parameters to use for profile generation |
If profstep
is set to 0, no profile matrix is generated.
Only first level MS data is read, not MS/MS, etc.)
A xcmsRaw
object.
