fill peaks, check raw data May 18, 2016, 01:28:20 PM I am using metaXCMS to generate a large peaktable with all features found from many different species of plants. I first processed these individual species using XCMS, RTCor,grouping etc. I then used metaXCMS generate the all species peaktable. I am concerned that this method will generate a lot of false negatives if a feature is not picked up by the original peak picking parameters. I'd like to use fillpeaks or getPeaks to fill out the all species peak table. Anyone done this or know of a way?
