artmsMsstatsSummary {artMS} | R Documentation

## Summarize the MSStats results and data quantification

### Description

Converts the MSStats results file to wide format (unique Protein ID and columns are the comparisons), as well as adds BioReplicate information about

- the Number of Unique Peptides,

- Spectral Counts

- Intensities for each protein. In cases where there are multiple values for a Protein-BioReplicate pair due to minute changes in sequence, the maximum value is taken for the pair. Any pairs without a value are assigned a value of NA.

### Usage

    artmsMsstatsSummary(
      evidence_file,
      prot_group_file,
      keys_file,
      results_file,
      return_df = FALSE,
      verbose = TRUE
    )

### Arguments

`evidence_file` | (char or data.frame) The filepath to the MaxQuant searched data (evidence) file (txt tab delimited file). Only works for the newer versions of the evidence file.
`prot_group_file` | (char) The filepath to the MaxQuant `proteinGroups.txt` file (txt tab delimited file) or data.frame
`keys_file` | (char) The filepath to the keys file used with MSStats (txt tab delimited file).
`results_file` | (char) The filepath to the MSStats results file in t he default long format (txt tab delimited file or data.frame).
`return_df` | (data.frame) Whether or not to return the results to the R environment upon completion. This is useful if this is being used in an R pipeline and you want to feed the results directly into the next stage of analysis via an R environment/terminal. Regardless, the results will be written to file. Default = FALSE
`verbose` | (logical) `TRUE` (default) shows function messages

### Value

(data.frame or txt file) with the summary

### Examples

    # Testing warning if files are not submitted
    test <- artmsMsstatsSummary(evidence_file = NULL,
                          prot_group_file = NULL,
                          keys_file = NULL,
                          results_file = NULL)
