Questions about RANSAC algorithm about mzmine3 HOT 4 CLOSED

Hi Jim,

The principle of the algorithm is described in the same text, just below the part that you highlighted. The algorithm uses the m/z and the RT of each peak (feature) for the alignment. If you need more details, you can check the code here:
https://github.com/mzmine/mzmine3/blob/0b4186061b0f04cf8b04459b336bf4852cad58bf/src/main/java/io/github/mzmine/modules/dataprocessing/align_ransac/RansacAlignerTask.java#L127

Hi Dr. Tomas,
Thanks for your response and I think I get the principle the algorithm now. But I have just one more question...If all the features which passes the filteration of the "RANSAC aligner" window are used for the alignment, is there a set of preferred parameters based on your experience? Thanks a lot!

Best regards & thanks

Hi Jim, I personally use the Join aligner. because it is conceptually more simple.
You should try to optimize the parameter values based on your dataset.

Thanks for all your response! : ) I'll try the optimization
