Data Analysis: Reprocessing Data
In contrast to data review, sequence reprocessing means that all the runs
of a sequence are reanalyzed in the sequence context, i.e. including
calibration table updates, parameters changes in the sequence table,
additions of new methods to the sequence, etc.
With the new data organization concept, the sequence container includes
all files needed for reprocessing: the data files, a copy of the sequence file,
and all the sequence methods originally employed with the acquisition.
Thus, in order to reprocess a sequence you simply have to load it into the
Navigation Table and the required tool set is available.

Note the following rules with regard to reprocessing:
• When loading a sequence container into the navigation table,
• All actions are performed on the sequence methods. If changed analysis
• The method loading settings of the Preferences dialog have no influence
• During reprocessing, the Batch (*.b) file, the sequence/single run log
When a sequence is reprocessed, all actions are performed on the sequence methods and

the DA.M of each data file is overwritten, including any changes you saved in these
methods. Optimizing DA.M during data review should be the last data analysis step after
final reprocessing has already been performed.
