Changing the Time Window for Analysis
The Start Time and End Time parameters in the Peak Find tab
define the time window within which peaks are found.
To change the Start Time and End Time parameters for all wells in
the open assay:
1 Select Analysis ïƒ Analysis Settings to open the Assay
Analysis Window, and then click the Peak Find Tab.
2 Change the parameters as necessary.
3 Click the OK button to save the setting, reanalyze the data, and
close the window.
Click the Apply button to apply the changes and reanalyze the
data, but keep the Assay Analysis window open.
Aligning or Unaligning the Marker Peaks
To perform data analysis for DNA, Protein, RNA, and Glycan
assays, the LabChip GX software aligns marker peaks included in
the sample wells with markers from the ladder.
• To view the unaligned data (spike rejected, filtered and baseline
corrected), choose Analysis ï‚® Turn Off Analysis.
• To re-enable analysis, choose Analysis  Turn On Analysis.
The default setting for this function is enabled. Turning off the
analysis displays the data without aligning the markers in the wells
and the ladders.
