136 -----------
|
|
137
|
|
138 After peak identification with xcmsSet, this tool groups the peaks which represent the same analyte across samples using overlapping m/z bins and calculation of smoothed peak distributions in chromatographic time. Allows rejection of features, which are only partially detected within the replicates of a sample class.

192 **mzClust**
|

|
|
196 **density**
|
|
197
|
|
198 | Groups peaks together across samples using overlapping m/z bins and calculation of smoothed peak distributions in chromatographic time.
|

199
|
|
200 **nearest**
|
|
201
|
|
202 | Groups peaks together across samples by creating a master peak list and assigning corresponding peaks from all samples. It is inspired by the alignment algorithm of mzMine.
