Both minFraction and minSamples are considered (combined with a logical AND), so minSamples does not override minFraction. Note however that minFraction does not mean that a chromatographic peak needs to be detected in minFraction of samples of all groups, but only in one of the groups.

Thank you for your reply - I see, only specifying minFraction as 0.5 and minSamples as 1, got features towards the higher mz that were only in 4% of only one group not 50% ( NA for other). I'm running again, specifying minFraction as 0.5 and minSamples as half of the smaller group and will see how it affects feature presence.
