Peak count filter - GC-MS project January 27, 2021, 07:42:34 AM Hello everyone,I am working on GC-TOFMS data with different sample groups and I am trying to understand, what the peak count filter means. According to the tutorial, it should remove peaks that are not fully detected in the alignment. But I don’t really understand, how this parameter deals with different sample groups – does it work group-wise or does it take simply all samples (regardless of the group they belong to) into account?For LC data, there is the additional option N% detected in at least one group but this is not available in a GC project.I hope you can help me.Best regardsBernadette Quote Selected

Re: Peak count filter - GC-MS project Reply #2 – February 01, 2021, 05:03:13 AM Thank you Hiroshi!I have metabolites that are only present in some sample classes and it would be necessary to set a filter for this. The peak count filter is not so helpful, as it deals simply with all samples and it does not take the different groups/classes into account.Best,Bernadette Quote Selected
