9 Data Review, Reprocessing and Batch Review
Navigation Table in Data Analysis
• sequence-related batch (*.b) file
• sequence-related logbook (*.log) file
During reprocessing, the individual methods DA.M for the data files are
updated as well as the batch file (*.b) file.
With the Data Analysis reprocessing functions, it is possible to modify the
sequence template (*.s) in the data container in order to change the multiplier,
dilution etc., or to use a different method for reprocessing. By default, the
Data Analysis reprocessing sequence parameter parts of method to run is set to
Reprocessing only, and the option Use Sequence Table Information is checked.
These predefined default values enable you to change the parameters in the
sequence template and run a reprocess without editing the Data Analysis
sequence parameters again.
If you have not explicitly changed the method in the sequence template, the
system uses the sequence methods stored in the sequence data container to
reprocess the sequence. These methods are the original methods used during
data acquisition. Note that, even if the option load DA method from data file in
Preferences / Signal/Review Options is selected, the system uses the sequence
container method for reprocessing, not the DA.M of the individual data files.
If particular method parameters need to be changed (for example, specify to
print to a *.xls file), the methods in the sequence container need to be
modified and saved. This general change is then applied to all data files during
reprocessing.
If you now want to use the updated sequence container method for further
data acquisition, you need to copy this method from the sequence data
container to one of the defined method paths. The new/updated method is
then available in the ChemStation Explorer in the method view as a master
method.
