Duplicate values created by fillChromPeaks

[frankyWk]

Our workflow is findChromPeaks, groupChromPeaks and fillChromPeaks. I am finding duplicate values in the output from fillChromPeaks - I have attached a sample file.
Is this expected behaviour where peaks are e.g. <1ppm apart and default FillChromPeaksParam() values are used?

fillChromPeaks() is only integrating values for features for which a chrom peak was missing in one or more files. So, it depends on the features that were defined. If you have features with less than 1 ppm apart then the function will integrate values for this. I guess you might have to check the settings for the groupChromPeaks() again.
