Hi all!
I have been using the AccurateMassSearch node in my pipeline for a long time with no issues, but yesterday I noticed that the resulting annotations fall outside of the ppm error value defined in the dialogue.
More specifically, in negative ion mode the ppm threshold actually used is 3x higher than the inputted one, while in positive it is 2x higher.
I also tried to change the mass error value using a flow variable, but the result did not change.
I am working on win10, KNIME 4.3.1, OpenMS nodes v2.6.0.202009301213, OpenMS v2.6.0
Any idea why this is happening?
Thanks,
Sonia
