The tool extracts mass spectral peaks from a data file (in either .mzML or .RAW format) and then filters these in accordance with user-defined parameter settings. All peaks remaining after filtering are hierarchically clustered in one-dimension, during which pairs of peaks with similar m/z values are grouped together if the difference between their m/z values, when divided by the average of their m/z values and multiplied by 1 x 10\ :sup:`6` \, equates to less-than the user-defined ppm error tolerance. **IMPORTANT:** when using .mzML files generated using the Proteowizard tool, SIM-type scans will only be treated as spectra if the ‘simAsSpectra’ filter was set to true during the conversion process, e.g.: *msconvert.exe example.raw* **--simAsSpectra** *--64 --zlib --filter "peakPicking true 1-”* ----------------- Parameters ---------- ***.mzml or *.raw files** (REQUIRED) - use one of the following inputs: * **Single or multiple .mzML or .raw file** * **Data collection** - use this option if .mzml or .raw files are contained within a Galaxy dataset collection. Dataset collections may be generated within the Galaxy environment. * **Zip file** from history - use this option if you have uploaded a \*.zip directory containing \*.mzML files (.raw files are not supported). **Filelist / Samplelist** (HIGHLY RECOMMENDED) - a table containing **filename** and **classLabel** information for each experimental sample. These column headers MUST be included in the first row of the table. For a standard DIMS experiment, users are advised to also include the following additional columns in order to ensure their data remains compatible with future versions of the dimspy processing pipeline: * **injectionOrder** - integer values ranging from 1 to i, where i is the total number of independent infusions performed as part of a DIMS experiment. e.g. if a study included 20 samples, each of which was injected as four independent replicates, there would be at least 20 * 4 injections, so i = 80 and the range for injection order would be from 1 to 80 in steps of 1. * **replicate** - integer value from 1 to r, indicating the order in which technical replicates of each study sample were injected in to the mass spectrometer, e.g. if study samples were analysed in quadruplicate, r = 4 and integer values are accordingly 1, 2, 3, 4. * **batch** - integer value from 1 to b, where b corresponds to the total number of batches analysed under define analysis conditions, for any given experiment. e.g. : if 4 independent plates of polar extracts were analysed in the positive ionisation mode, then valid values for batch are 1, 2, 3 and 4. * **NOTE**: for DIMS experiments, “batch” is synonymous with plate, i.e. each independent plate analysed under a given analytical configuration may be considered an individual “batch”. This file: * must be uploaded to (or be accessible to) the active Galaxy history in order to allow for its selection in the Filelist / Samplelist drop-down menu. The file list / sample list may be created in .txt format, however, when imported in to the active Galaxy history, users must ensure to select ‘.tabular’ format. * may include additional columns, e.g. additional metadata relating to study samples. Ensure that columns names do not conflict with existing column names. | @example_filelist@ | **Function to calculate the noise from each scan** (REQUIRED; default = **median**) - toggle requiring selection of one option from the drop-down menu to indicate the preferred algorithm to apply for spectral noise calculation. The following options are available: * **Median** - the median of all peak intensities within a given file is used as the noise value. This simplistic approach to estimating noise may be suitable for spectra with many low abundant features, but it is generally not recommended for use when spectra contain relatively few low-abundant peaks e.g. MS2 spectra. * **Mean** - the unweighted mean average of all peak intensities within a given file is used as the noise value. This simplistic approach to estimating noise may be suitable for spectra with many low abundant features, but it is generally not recommended for use when spectra contain relatively few low-abundant peaks e.g. MS2 spectra. * **Mean absolute deviation (MAD)** - the noise value is set as the mean of the absolute differences between peak intensities and the mean peak intensity (calculated across all peak intensities within a given file). * **Xcalibur** - the noise value is calculated using the proprietary algorithms contained in Thermo Fisher Scientific’s reader libdrary. This option should only be applied when you are processing .RAW files. | **Signal-to-noise ratio (SNR) threshold** (REQUIRED; default = 3.0) - a numerical value from 0 upwards. Peaks with a signal-to-noise ratio (SNR) less-than or equal-to this value will be removed from the output peaklist. In the comprehensive peaklist output (.tsv-formatted), peaks with a SNR below the user-defined threshold will have a ‘0’ in the ‘snr-flag’ column, which indicates that they should be ignored in downstream processing procedures. Peaks with a SNR exceeding the user-defined cutoff will have a ‘1’ in the ‘snr-flag’ column. | **Filter specific scan windows or scan events?** (OPTIONAL; default = **No**) - a boolean toggle where: * **No** - do not perform scan event filtering; * **Yes** - filter specific scan events * when selected, users must specify whether to 'Exclude' or 'Include' specific scan events. This can be useful if, for example, a user wishes to run the Process Scans tool on only a subset of scan types collected in each file. e.g. some SIM stitch acquisitions may be initiated with an initial 30 second stabilisation period, during which full-scan data are acquired. This full-scan data can be excluded from further consideration by using the ‘exclude’ toggle. * Included or excluded scan events must be fully defined by the user, else ALL scan events will be included. To do so: * Click the '+ Description' button and insert the start and stop m/z values for the scan event to be included/excluded.. * Select the 'scan type' to be filtered. Options are: 'Full scan' or 'SIM scan' * Click '+ Description' to 'Exclude/Include' an additional scan event. | **Show options for multiple scans** (OPTIONAL) * **Minimum number of scans required for each m/z window or event within a raw/mzML data file** (default = 1) - A positive integer equal-to or greater-than 1 that specifies the number of times a given scan event must occur in a given file in order for this scan event to be included in downstream processing steps and in the output .tsv-formatted peaklist. * **ppm error tolerance** (default = 2.0) - A positive numerical value equal-to or greater-than zero. This option impacts the clustering of peaks extracted from an input file. If the mass-to-charge ratios of two peaks, when divided by the average of their mass-to-charge ratios and then multiplied by 1 × 106, is equal-to or less-than this user-defined value, then these peaks are clustered together as a single peak. Clustering is applied across all replicates of a given scan event type i.e. with a given input file, all peaks detected in the three replicates of a 50-400 m/z scan event would undergo assessment for the need for clustering. * **Minimum fraction (i.e. percentage; default = 0, i.e. skip) of scans a peak has to be present in** - A numerical value from 0 to 1 that specifies the minimum proportion of scans a given mass spectral peak must be detected in, in order for it to be kept in the output peaklist. Here, scans refers to replicates of the same scan event type, i.e. if set to 0.33, then a peak would need to be detected in at least 1 of the 3 replicates of a given scan event type. The ppm error specified by the user will significantly impact which peaks fulfil this criteria. * **Relative standard deviation threshold** (default = 0, i.e. skip) - A numerical value equal-to or greater-than 0. If greater than 0, then peaks whose intensity values have a percent relative standard deviation (otherwise termed the percent coefficient of variation) greater-than this value are excluded from the output peaklist. | **Show advanced options** (OPTIONAL) * **Skip SIM-stitching** (REQUIRED; default = **No**) - a boolean toggle where: * **No** - perform SIM stitching * **Yes** - skip the processing step where (SIM) windows are 'stitched' or 'joined' together. Use this option if you would like to process individual scan/SIM windows (events/ranges) without 'stitching' them. * **Remove m/z range(s)** (OPTIONAL) - this option allows for specific regions of the output peak matrices to be deleted by the user - this option may be useful for removing sections of a spectrum known to correspond to system noise peaks. * **Start m/z of removal range** - a positive numerical value corresponding to the lowest m/z value in the spectral region to be removed. * **End m/z of removal range** - a positive numerical value corresponding to the highest m/z value in the spectral region to be removed (must be greater than the ‘start m/z of removal range’). * **Relative intensity threshold used to remove ringing artefacts** (OPTIONAL) - Fourier transform-based mass spectra often contain peaks (ringing artefacts) around spectral features arising from detection of charged, gas-phase bio-molecules. * A positive numerical value indicating the required relative intensity a peak must exceed (with reference to the largest peak in a cluster of peaks) in order to be retained. ---------------------------------- Output file(s) -------------- | The Process scans (and SIM stitch) tool will output three file types: 1) **A HDF5 file** containing the processed peaklists 2) **A processed peaklist**, presented in tabular format, for each study sample specified in the filelist/samplelist. Each row corresponds to a single peak. Where multiple peaks were grouped together during the hierarchical clustering process, each peaklist metric constitutes an average of the groups’ values. Metrics included in the peaklist are: @help_columns_peaklist@ @example_peaklist@ | 3) **A tabular “report” file** that details, for each scan event processed in each file: * Scan range of scan event * Scan number of scan event * Number of peaks detected in scan event * Median RSD of peaks detected in each scan event type (only applied if number of scans for a given scan event is <![CDATA[ > ]]> 1 ----------------------------------- @github_developers_contributors@ @license@ RawFileReader reading tool.
