|
64 For each sample, identify peak groups where that sample is not
|
|
|
65 represented. For each of those peak groups, integrate the signal
|
|
|
66 in the region of that peak group and create a new peak.
|
|
|
67
|
|
|
68 According to the type of raw-data there are 2
|
|
|
69 different methods available. for filling gcms/lcms data the method
|
|
|
70 "chrom" integrates raw-data in the chromatographic domain, whereas
|
|
|
71 "MSW" is used for peaklists without retention-time information
|
|
|
72 like those from direct-infusion spectra.

130 | This method produces intensity values for those missing samples by integrating raw data in peak group region. In a given group, the start and ending retention time points for integration are defined by the median start and end points of the other detected peaks. The start and end m/z values are similarly determined. Intensities can be still be zero, which is a rather unusual intensity for a peak. This is the case if e.g. the raw data was threshholded, and the integration area contains no actual raw intensities, or if one sample is miscalibrated, such the raw data points are (just) outside the integration area.
|
|
|
131 | Importantly, if retention time correction data is available, the alignment information is used to more precisely integrate the propper region of the raw data. If the corrected retention time is beyond the end of the raw data, the value will be not-a-number (NaN).
