Hi Trevor,
yes, apQuant works for FAIMS data and treats FAIMS CVs separately. Quantification for peptides occuring in multiple CVs will be summed up.
I did not have the chance to test the Fragpipe node yet. But if you switch to the respective score and choose a meaningful score threshold it should work.
Where is the Fragpipe node available? Can you send me a link.
Kind regards, Gerhard
