format_david {FGNet} | R Documentation

## Format DAVID output

### Description

Format DAVID 'functional annotation and clustering' output to use with FGNet.

### Usage

    format_david(fileName,
    jobName = NULL,
    geneLabels = NULL,
    moveFile = FALSE,
    downloadFile=TRUE)

### Arguments

`fileName` | character. URL or local file with the results of a DAVID analysis, for example, performed at DAVID's Website (http://david.abcc.ncifcrf.gov/summary.jsp). In case of local file, it should be the absolute path to the .txt file (whole location from root to the file including file name: "C:\\Documents\\23424203.txt", "/home/user/2342342.txt").
`jobName` | character. Folder name and prefix for the formatted files.
`geneLabels` | named character vector. Gene name or label to use in the report/plots instead of the original gene ID. The vector names should be the gene ID and the content of the vector the gene label. The resulting geneTermSets table will contain the original gene ID column (geneIDs) and the label column (Genes).
`moveFile` | logical. If TRUE the original file is moved to the new location. If FALSE, the file is copied.
`downloadFile` | logical. If TRUE, the result files are saved in the current directory (required to generate report).

### Value

Invisible list with the folowing fields:
`queryArgs` list with the arguments for the query.

`clusters` data.frame containing the clusters and their information:

- Cluster: Cluster ID.

- nGenes: Number of genes in the cluster.

- ClusterEnrichmentScore: Score for the cluster.

- Genes: Genes in the cluster.

- Terms: Terms in the cluster.

- keyWordsTerm: Term is the most representative of the terms in the cluster based on keywords.

`geneTermSets` data.frame containing the gene-term sets that support each cluster.

- Cluster: Number (id) of the cluster the gene-term set belongs to.

- ClusterEnrichmentScore: Score for the cluster. Same value for all terms in each cluster.

- Category: Type of annotation of the term (i.e. GO, Kegg...)

- Terms: Term in the gene-term set.

- Genes: Genes in the gene-term set.

- GenesIDs: In case GeneLabels was provided, original gene ID.

- Other stats: Count, PValue, List.Total, Pop.Hits, Pop.Total, Fold.Enrichment, Bonferroni, Benjamini, FDR.

`fileName` .txt file with the formatted FEA results.
