Load Raw Data Files for Processing
➢
After selecting the raw data to be analyzed, load the files into the Currently Loaded file list
below using one of two methods:
1.
Use the load button ( ) to load selected files from the Select/Quickview list.
2.
Use the remote load button (
) to select files from another folder with a dialog
window.
➢
The Currently Loaded file list may be modified with the control buttons to the right of the
frame.
Processing Raw Data
Each raw data file is analyzed to count and measure particles detected during acquisition. The
result of this analysis is a Spectradyne Stats file that contains detailed information about all
particles detected during the acquisition as well as the acquisition itself.
Procedure for Processing Raw Data
➢
The Process Raw Data tab of the Data Viewer contains all the controls for processing raw
data, as well as relevant measured values for the selected raw data file.
➢
The default processing parameter values are appropriate for use in most cases. These
default values are the same as those used by the Auto-analysis Engine during acquisition:
❖
Peak Detection Threshold: 3.0 x the standard deviation of the baseline noise.
❖
Fit Width: 4.0 x the mean transit time of high signal-to-noise particle events.
➢
The above parameters can be customized for more in-depth analysis using the entries in
the Processing Parameters frame.
➢
“Apply Default Peak Filters” box:
❖
Choose whether or not to apply default peak filters to the data when processed
(recommended).
➢
To analyze the raw data, use the controls in the Processing Actions frame:
❖
“Process Selected”: Processes only the
currently selected raw data file from the
Currently Loaded list.
❖
“Process All”: Processes all raw files in the Currently Loaded
files list using the same
(adaptive) parameters.
❖
“Stop”: Interrupts processing of the current raw
file with no partial data saved and
stops batch processing.
