## NormalyzerDE pipeline entry point

### Description

This function is the main execution point for the normalization part of the NormalyzerDE analysis pipeline. When executed it performs the following steps:

### Usage

    normalyzer(jobName, designPath = NULL, dataPath = NULL,
      experimentObj = NULL, outputDir = ".", forceAllMethods = FALSE,
      omitLowAbundSamples = FALSE, sampleAbundThres = 5,
      tinyRunThres = 50, requireReplicates = TRUE,
      normalizeRetentionTime = TRUE, plotRows = 3, plotCols = 4,
      zeroToNA = FALSE, sampleColName = "sample", groupColName = "group",
      inputFormat = "default", skipAnalysis = FALSE, quiet = FALSE,
      noLogTransform = FALSE, rtStepSizeMinutes = 1,
      rtWindowMinCount = 100, rtWindowShifts = 1,
      rtWindowMergeMethod = "mean")

### Arguments

`jobName` | Give the current run a name.
`designPath` | Path to file containing design matrix.
`dataPath` | Specify an output directory for generated files. Defaults to current working directory.
`experimentObj` | SummarizedExperiment object, can be provided as input as alternative to 'designPath' and 'dataPath'
`outputDir` | Directory where results folder is created.
`forceAllMethods` | Debugging function. Run all normalizations even if they aren't in the recommended range of number of values
`omitLowAbundSamples` | Automatically remove samples with fewer non-NA values compared to threshold given by sampleAbundThres. Will otherwise stop with error message if such sample is encountered.
`sampleAbundThres` | Threshold for omitting low-abundant samples. Is by default set to 15.
`tinyRunThres` | If total number of features is less than this, a limited run is performed.
`requireReplicates` | Require multiple samples per condition to pass input validation.
`normalizeRetentionTime` | Perform normalizations over retention time.
`plotRows` | Number of plot-rows in output documentation.
`plotCols` | Number of plot-columns in output documentation.
`zeroToNA` | Convert zero values to NA.
`sampleColName` | Column name in design matrix containing sample IDs.
`groupColName` | Column name in design matrix containing condition IDs.
`inputFormat` | Type of input format.
`skipAnalysis` | Only perform normalization steps.
`quiet` | Omit status messages printed during run.
`noLogTransform` | Don't log-transform the input.
`rtStepSizeMinutes` | Retention time normalization window size.
`rtWindowMinCount` | Minimum number of datapoints in each retention-time segment.
`rtWindowShifts` | Number of layered retention time normalized windows.
`rtWindowMergeMethod` | Merge approach for layered retention time windows.

### Details

1: Loads the data matrix containing expression values and optional annotations, as well as the design matrix containing the experimental setup 2: Performs input data verification to validate that the data is in correct format. This step captures many common formatting errors. It returns an instance of the NormalyzerDataset class representing the unprocessed data. 3: Calculate a range of normalizations for the dataset. The result is provided as a NormalyzerResults object containing the resulting data matrices from each normalization. 4: Analyze the normalizations and generate performance measures for each of the normalized datasets. This result is provided as a NormalyzerEvaluationResults object. 5: Output the matrices containing the normalized datasets to files. 6: Generate visualizations overviewing the performance measures and write them to a PDF report.

### Value

None

        designPath=design_path,
        dataPath=data_path,
        outputDir=out_dir)
