Preferences - Sequence Tab

On the Sequence tab, the user has the choice of two different data storage

models. These modes define how the sequence data are stored in the

ChemStation.

In this mode of data storage, there is a robust and permanent link between the

raw data and the method. Each data file, whether acquired within a sequence

or as a single run, has links to at least two methods: the method that was used

to acquire the data, and the one that was used for data analysis.

The sequence data are stored in a sequence data container using a defined

sequence container name. You can specify the naming conventions (Name

Pattern) for these sequence containers in the Sequence tab of the Preferences

dialog box. If no name pattern is specified, a default sequence name pattern is

used. The Sequence Tab is used only for data acquisition and therefore is

present only for online systems.

The sequence name pattern can contain various sections. The system creates a

name for your sequence data container that is determined by the sequence

name pattern sections you select. All data files, methods, the sequence

logbook, the sequence_name.s file and the sequence_name.b file belonging to

this particular sequence are stored in the sequence data container. The

sequence data container is created when the sequence is started.

The sequence (.s) files are used as sequence templates, and this concept allows

you to run any sequences.s file multiple times without overwriting existing

data and without changing the sequence parameters. If neither counter nor

time are used in the sequence name pattern, the system introduces a counter

automatically to avoid overwriting data. For the second, third and all

subsequent sequences using the same sequence template, a counter is added

to the sequence container name.
