Resampler can be used to transform an LC/MS map into a resampled map.

When writing an peak file, all spectra are resampled with a new sampling rate. The number of spectra does not change.

The command line parameters of this tool are:

Usage:
  Resampler <options>

Options (mandatory options marked with '*'):
  -in <file>*                      Input file  (valid formats: 'mzML')
  -out <file>*                     Output file in mzML format (valid formats: 'mzML')
  -sampling_rate <rate>            New sampling rate in m/z dimension (in Th unless ppm flag is set) (default: '0.1') (min: '0.0')
  -ppm                             Sampling_rate is given in ppm
  -align_sampling                  Ensures that sampling is performed equally across the map (same raster is used for all spectra)
  -min_int_cutoff <min intensity>  Intensity cutoff for peaks to be stored in output spectrum (only peaks above this cutoff will be stored, -1 means store all data) (default: '-1.0')
                                   
Common TOPP options:
  -ini <file>                      Use the given TOPP INI file
  -threads <n>                     Sets the number of threads allowed to be used by the TOPP tool (default: '1')
  -write_ini <file>                Writes the default configuration file
  --help                           Shows options
  --helphelp                       Shows all options (including advanced)
