I just upgraded to the newest horae-031 package It looks to me that the new Artemis version (0.7.001) doesn't have that nice button "use previous background" anymore. If I am not mistaken the button allowed to subtract background fitted previously. Am I? Is it somehow hidden in the new version?
I changed how the concept of using background subtracted data is implemented. Like many things with Artemis, it is underdocumented. In the Data menu is a option for "Save background subtracted as chi(k)". This will subtract the background you just performed form the data and save that chi(k) function to a file. The default behavior is to save the new chi(k) file in the project workspace so that it gets inlcuded in the project when the project is saved. Then, Artemis will ask if you want to replace the current data with the background subtracted data. You can say yes or no, as you wish. As you continue working, it is easy to switch between the original data and the background subtracted data because both are stored in the project work space. File menu -> "Project data" -> "Import project data" is a shortcut to all the data stored in the project work space. This underscores one of the advantages of using zip files as project files. It is easy to carry around many data files along with a project and then quickly switch between them without changing the model or stopping and restarting Artemis. FYI. Difference spectra work essentially the same way. The chi(k) containing the data minus a sum of paths is saved to the workspace and you are asked if you want to change from the original data to the difference spectrum. All clear?
