I currently need to evaluate some spectra and would like to simplify this process using Origin Python. To do this, I read the raw data into Origin, run a filter over the data and create the graph including the plot and output it. In the following, I would like to use the x-function pa to run a pre-built theme over the data. The code snippet looks like this:
#MyTheme = op.path('p') + "Themes\Spectraanalyisis.ois" #Read the theme Spectraanalyisis #MyTheme = op.path('p') + "Themes\Peakfinder.ois" #reading the Peakfinder theme #wks.lt_exec('pa iy:=col(B) smode:=1 theme:=MyTheme') #does not work like this wks.lt_exec('pa iy:=col(B) smode:=1 theme:=Peakfinder') #Calling the theme
As you can see, I'm trying to do the whole thing with a LabTalk function. The Peakfinder theme stores the correct x-coordinates and y-coordinates of the peaks and puts them in a new sheet. The Spectraanalyisis theme retrieves the peak analyzer (pro) and creates the corresponding Plot_Data, Integration_Result, etc. sheets. Unfortunately, however, it does not create the additional graphs as it does when run manually. Several questions arise for me:
Is it possible to get the generated data processed as after manual execution without running new fit functions etc. over it? (Peakfinder - x-coordinate as label at the peak in the graph, peak analyzer (pro) with Gaussfits graph etc.). Can I also access the x functions directly with python? Can I assign the themes to a variable as in the comment out attempt and then retrieve it later? (Like MyTheme)
My Origin Version is OriginPro 2023 (64-bit) 10.0.0.154.
Thank you for your help. I looked at the wks.lt_exec('pa iy:=(1,2) smode:=1 theme:=myTheme') again and found that I made a fault at the themes Name. After I changed it, it worked pretty much as intended.
In the Origin folder the themes are saved as 0-xFunctionName-ThemeName.osi. I changed the name in just ThemeName.osi which somehow crashed the retrieval of the pa-xFunction. It needs to be in the original order 0-xFunctionName-ThemeName.osi. Futhermore you can't use theme:=0-xFunctionName-ThemeName.osi as well. It needs to be the name you saved it with.
The part I could not solve is to save the theme in the projectfolder itself. I need the program on a USB to just plug it in and starting the programm. Is it somehow possible to retrieve the theme from another folder then the default one?
Right now it is not possible to load the theme by its file path. You have to drag the theme file to the Origin workspace to install it first. I have created a ticket (ORG-27498) to report this request, and we will see if any improvements are needed.
