Polarity is defined on the General tab and will affect values on the Annotation and Identification (adducts) tabs. Job results will be misleading if this value is not correctly defined.
The current parameter set is read-only. Use Create New button below to modify parameters to suit your job.
Allowable retention time deviations, in seconds. In more detail: bandwidth (standard deviation or half width at half maximum) of gaussian smoothing kernel to apply to the peak density chromatogram
minfrac
minimum fraction of samples necessary in at least one of the sample groups for it to be a valid group
mzwid
width of overlapping m/z slices to use for creating peak density chromatograms and grouping peaks across samples
Default width for extracted ion chromatograms in seconds

Note:
Correct mass calibration gaps
Correction of mass calibration gaps - subtract LockMass scans from data. Only applicable for Waters instruments !
Bypass file sanity check
All uploaded files are normally checked for different types of errors and inconsistencies. This option disables the file sanity check. Unfortunately necessary for certain types of GC/MS data when used with centWave. Only disable this check if you know what you are doing!
