Hello Besim and thank you for the bug report. There is definitely a mishandling of the case where a particular tag name is included in another tag name. I made the necessary modifications in the branch "fix-merge-issue", available for download here: https://github.com/RNA-FRETools/MASH-FRET/archive/refs/heads/fix-merge-issue.zip

Can you tell me if it is working for you? In this case, I will merge this modification in the main branch.

Dear Mélodie,

Thank you very much for the fix! Yes, it is working now. However, I have a small issue with merging. We can't merge some traces due to different frame rates. I assume the root cause for this is that the frame rate given by the measurements differs in the last digit, stemming from a rounding up or down. How can we tell the software to accept that difference?

Hi Besim,Thank you for your feedback. I see the problem and I will think about a solution. But first I need to close this issue to open a new one ;)
