Analysis settings and study folder

To be able to analyse data with EMEGS (Qt version), you have to setup a studyfolder containing your data and analysis options.

Analysis settings are stored in the EMEGS definition file, which must be named “qemegsdef.ini” and must live top level (not in a subdirectory) inside every study folder. To create a study folder with a standard definition file, select “New study” from the settings menu and select location and name of the new studyfolder on the upcoming dialog.

Select this studyfolder for the current analysis using “Browse for studyfolder” button on the studyfolder toolbar. On the upcoming dialog select a study folder and push Ok.

The path of the selected folder will then appear in the studyfolder path dropdown box. A small symbol to the right of this dropdown box (either a check mark or a warning sign) indicates wether the selectd folder is valid and can be used for analysis. EMEGS (Qt version) will remember a number of recently used study folder and make them quickly available in the studyfolder dropdownbox. Only if the selected study folder is valid, the open data file button will become enabled and study options can be adjusted using the “configure study”-dialog, available from the settings menu:

This dialog is THE central configuration interface for all EMEGS (Qt version) functions. It’s content is stored in the study definition file to make it persistent and specific to a given dataset. It contains sections for every analysis type and additional pages for channel naming, optional channels, sensor configurations and SQL configuration.

After selecting a study folder, select the dataformat of your data files from the dataformat button. Available formats and their corresponding icons are the following. Some of these are not yet supported and will be disabled. (And some may not work with new amplifiers, the routines are quite old!)
