                abstract = {Metabolomic data are frequently acquired using chromatographically coupled mass spectrometry
                (MS) platforms. For such datasets, the first step in data analysis relies on feature detection, where a
                feature is defined by a mass and retention time. While a feature typically is derived from a single
                compound, a spectrum of mass signals is more a more-accurate representation of the mass spectrometric
                signal for a given metabolite. Here, we report a novel feature grouping method that operates in an
                unsupervised manner to group signals from MS data into spectra without relying on predictability of the
                in-source phenomenon. We additionally address a fundamental bottleneck in metabolomics, annotation of MS
                level signals, by incorporating indiscriminant MS/MS (idMS/MS) data implicitly: feature detection is
                performed on both MS and idMS/MS data, and feature-feature relationships are determined simultaneously
                from the MS and idMS/MS data. This approach facilitates identification of metabolites using in-source MS
                and/or idMS/MS spectra from a single experiment, reduces quantitative analytical variation compared to
                single-feature measures, and decreases false positive annotations of unpredictable phenomenon as novel
                compounds. This tool is released as a freely available R package, called RAMClustR, and is sufficiently
                versatile to group features from any chromatographic-spectrometric platform or feature-finding software.

        Background
            Metabolomics
                Metabolomics is frequently performed using chromatographically coupled mass spectrometry, with gas
                chromatography, liquid chromatography, and capillary electrophoresis being the most frequently utilized
                methods of separation. The coupling of chromatography to mass spectrometry is enabled with an
                appropriate ionization source - electron impact (EI) for gas phase separations and electrospray
                ionization (ESI) for liquid phase separations. XCMS is a commonly used tool to detect all the signals
                from a metabolomics dataset, generating aligned features, where a feature is represented by a mass and
                retention time. Each feature is presumed to derive from a single compound. However, each compound is
                represented by several features. With any ionization method, isotopic peaks will be observed reflective
                of the elemental composition of the analyte. In EI, fragmentation is a byproduct of ionization, and has
                driven the generation of large mass spectral libraries. In ESI, in-source fragmentation frequently
                occurs, the magnitude of which is compound dependent, with more labile compounds being more prone to
                in-source fragmentation. ESI can also product multiple adduct forms (protonated, potassiated, sodiated,
                ammoniated...), and can produce multimers (i.e. [2M+H]+, [3M+K]+, etc) and multiple charged species
                ([M+2H]++). This can become further complicated by considering combinations of these phenomena. For
                example [2M+3H]+++ (triply charged dimer) or an in-source fragment of a dimer.

            RAMClustR approach
                RAMClustR was designed to group features designed from the same compound using an approach which is
                **1.** unsupervised, **2.** platform agnostic, and **3.** devoid of curated rules, as the depth of
                understanding of these processes is insufficient to enable accurate curation/prediction of all phenomenon
                that may occur. We achieve this by making two assumptions. The first is that two features derived
                from the same compound with have (approximately) the same retention time. The second is that two
                features derived from the same compound will have (approximately) the same quantitative trend across
                all samples in the xcms sample set. From these assumptions, we can calculate a retention time
                similarity score and a correlational similarity score for each feature pair. A high similarity score
                for both retention time and correlation indicates a strong probability that two features derive from
                the same compound. Since both conditions must be met, the product of the two similarity scores provides
                the best approximation of the total similarity score - i.e. a feature pair with retention time similarity
                of 1 and correlational similarity of 0 is unlikely to derive from one compound - 1 x 0 = 0, the final
                similarity score is zero, indicating the two features represent two different compounds. Similarly, a
                feature pair with retention time similarity of 0 and correlational similarity of 1 is unlikely to derive
                from one compound - 0 x 1 = 0. Alternatively - a feature pair with retention time similarity of 1 and
                correlational similarity of 1 is likely to derive from one compound - 1 x 1 = 1.

        The RAMClustR algorithm is built on creating similarity scores for all pairs of features, submitting
        this score matrix for hierarchical clustering, and then cutting the resulting dendrogram into neat
        chunks using the dynamicTreeCut package - where each 'chunk' of the dendrogram results in a group of
        features likely to be derived from a single compound. Importantly, this is achieved without looking for
        specific phenomenon (i.e. sodiation), meaning that grouping can be performed on any dataset, whether it
        is positive or negative ionization mode, EI or ESI, LC-MS GC-MS or CE-MS, in-source fragment or complex
        adduction event, and predictable or unpredictable signals.
