Reinstalling the program may fix this problem. I reinstalled it, but the issue persists. The application doesn't launch after I download the .exe file. Could you please suggest a possible solution?

Dear Michał, In order to provide correct normalized percentages one would have to be sure that all elements present in the sample are measured and that all the measured elements actually come from the sample. Those conditions cannot be warranted and the normalization cannot be applied. Therefore to say 0.05 mass fraction or 5 % mass proportion is just a question of taste and I do not see any added benefit. Without going any further, in the steel example provided with PyMca, the measured mass fractions for Cr, V, Fe, Ni and Mn are correct and, for instance, to go from an Fe mass fraction of 0.64 to a 64 % concentration does not require a huge effort. Furthermore, the sum of the mass fractions of those elements amounts to 0.97. This particular case is quite good, but a normalization to 100 % would modify the concentrations of all the elements when in fact, the actual sample composition contains more than 2 % of Mo that is not measured due to the used excitation energy.

Dear Armando, I use pyMCA to analyze elemental content in metal alloys. However, metallurgists are accustomed to using percentages instead of mass fractions. Would it be possible to add a switch to display the analysis result as a percentage? To obtain the result in percentages, I slightly modified the program code, but not everyone knows how to do this. Another interesting option would be the ability to normalize the results to 100%. --- Best regards, Michał Olejnik Poland |

Dear Armando, Thank you for the responses. I have included the multiple energies as you advised and both the K alpha and K beta peaks for Compton and Rayleigh scattering have appeared. However, just as the earlier case, the simulated peaks are more intense than the experimental counterparts. Kindly see the attached spectra.

But have you filled all the energies emitted by your tube??? Run your simulation with something similar to the table below. DISCLAIMER: I do not know if your tube has anything to select a single energy nor if the ratios below apply to the emission of your tube. In the configuration you sent us you are using a monochromatic beam. Without optical elements, you must have multiple energies coming out of your X-ray tube and not a single one.

Dear members, Many thanks for the responses Armando. I have double clicked the second energy table but the results are still the same. As you can see from the scatter peaks, why is the simulated one more intense than the experimental counterpart.

Dear Edward, My first impression is that you are considering Mo-Ka as exctation beam and that you have forgotten about Mo-Kb. (double click on the second energy of the energy table to turn-it pink) Without the original spectrum and the original cfg file it is difficult to say more.

Dear members, I have attempted to simulate experimental spectrum using XMI-MSIM pymca software but the simulated scatter peaks are not matching with their experimental counterparts. I would like to know why and how to correct it. See the attached spectra. Thank you in advance. Edward Sichangi |

Dear Joen, Thanks for the report. I have just reproduced the issue. Basically anything opening a thread in the ROI Imaging Tool crashes. For instance, the PCA analysis crashes too. I will check if it can be easily solved. It might be just dependent on the Qt binding used or version (PySide6 in the frozen binary).

Hello, That often happens to me and that is usually linked to a limitation in RAM. Check that by monitoring the memory use when launching NNMA.

Hello, Do you have an energy of the incoming photons in your configuration (Advanced Fit/Configure/Beam tab) ? If that energy is below 18.04800 keV, then K and L lines cannot be selected because Rn cannot be ionized on those shells but L, L2, L3 and M remain accessible.

Dear PyMCA Experts, I hope this message finds you well. I am currently working on XRF data analysis using PyMCA and have encountered an issue that I hope you could help me with. Specifically, I've noticed that some peaks in the fitting part of the software are disabled. For example, in the case of Rn, peaks such as K, Ka, Kb, and L1 are disabled, whereas L, L1, and L3 are enabled. However, the Peak Identifier estimates the presence of the Rn Ka line. Any assistance or advice on this matter would be greatly appreciated. Thank you in advance for your time and support. Best regards, Mohammad Rezaei Pandari Ph.D. in Photonics Gmail: rez...@gm...
