Frequently asked questions (FAQ)

  • Q: How do I start an analysis?
  • A: Right click the analysis file from the project explorer and select 'Run analysis' from the pop-up menu.
  • Q: Why can't I edit my model?
  • A: It is not (or no longer) possible to edit the model files directly. Rather they are dragged onto the analysis scheme editor from which they can be edited.
  • Q: How do I connect two components/containers together in the analysis scheme editor?
  • A: Press CTRL, click on the name of the container and drag towards another (on the Mac: CMD+CTRL). In this way, a model container can be linked to a dataset container and a dataset container can be linked to an output container.
  • Q: I am getting an error “the analysis did not return valid results, try again with different parameters” if I try to run an analysis with more than 0 iterations.
  • A: There are two primary reasons for this error message. Either the starting values for your parameters are way off, or there is too much freedom in your model for the fitting algorithm to function and you need to constraint the freedom in your model somehow. This can be done either by fixing certain parameters, or by imposing additional spectral constraints - what is best depends on your specific situation. Note that this problem is usually related to target models in which you typically try to estimate more parameters than in global analysis.
  • Q: I am getting an error message “Unable to connect to the Glotaran Update Center because of Zero sized file reported at”
  • A: If your network setting are correct, this is most likely due to a mis-configured update center. The easiest solution to this problem is to go to http://glotaran.org/downloads and download the latest version of Glotaran in which this problem has been fixed. Otherwise you can attempt to fix this manually (see a list of automatic update centers) for Glotaran.
  • Q: My question about Glotaran is not answered by this FAQ.
  • A: Please feel free to contact us with your question.
