Subtracting background filter available as plugin (Q678)
The information in this article applies to:
The plugin named 'Subtract Background' conducts a simple correction by subtracting a selected background observation (typically spectrum) from all other observations. Please note that secondary datasets cannot be imported after applying this filter.
To download the plugin linked below, extract the .exe and .dll-files and install as follows:
- Run the .exe-file and follow the instructions in the installation program.
- Start SIMCA®.
- In File | Options | SIMCA® options tab More Options, you will find the path of the default plugin directory (for SIMCA® 13 the SIMCA® Options dialog is opened directly from the File tab; for SIMCA®-P+ 12 click View | General Options). This directory can be changed, as needed.
- Add the appropriate .dll in the plugin directory and re-start SIMCA®. After installation the filter is available by clicking Spectral filters in the Modify dataset group on the Data tab (for SIMCA®-P+ 12 click Dataset | Spectral Filters). NOTE! This is not a spectral filter but can be accessed from that menu. This feature has been tested under Windows 7 for a few datasets. The .dll has not been validated.
