output_update {systemPipeR}

R Documentation

Updates the output files paths in the SYSargs2 object

Description

After executing all the command-lines by the runCommadline function, the output files can be created in specific directories rather then results in a particular directory. Also, the runCommadline function allows converting the SAM file outputs to sorted and indexed BAM files. Thus, the output_update function allows updating the location of these files in the output of the SYSargs2 object.

Usage

output_update(args, dir = FALSE, dir.name = NULL, replace = FALSE, extension = NULL, make_bam=FALSE, del_sam=TRUE)

Arguments

args	object of class SYSargs2.
dir	assign TRUE to update the location of the output files in the args object accordingly with the workflow name directory. Default is dir=FALSE.
dir.name	if the results directory name is not specified in the input file, it is possible to specify here the name. This argument is required if the path name return NULL from the input file. Default is dir.name=NULL.
replace	replace the extension for selected output files in the args object. Default is replace=FALSE.
extension	object of class "character" storing the current extension of the files and the respective replacement. For example, runCommandline function by default autodetects SAM file outputs in the args object and create the BAM files. In order to update the output of args object, the extension argument should be set: extension = c(".sam", ".bam").
make_bam	Auto detects SAM file outputs and update them on the SYSargs2 object for sorted and indexed BAM files. Default is make_bam=FALSE. This argument should be used in integration with runCommandline function.
del_sam	This option allows deleting the SAM files created when the make_BAM converts the SAM files to sorted and indexed BAM files. Default is del_sam=TRUE.

Value

SYSargs2 object with output location files updated.

Examples

 
## Construct SYSargs2 object from CWl param, CWL input, and targets files 
targets <- system.file("extdata", "targets.txt", package="systemPipeR")
dir_path <- system.file("extdata/cwl", package="systemPipeR")
WF <- loadWorkflow(targets=targets, wf_file="hisat2/hisat2-mapping-se.cwl", 
                  input_file="hisat2/hisat2-mapping-se.yml", dir_path=dir_path)
WF <- renderWF(WF, inputvars=c(FileName="_FASTQ_PATH1_", SampleName="_SampleName_"))
WF
output(WF)

## Not run: 
runCommandline(args=WF, make_bam=TRUE)
## Output paths update
WF <- output_update(WF, dir=FALSE, replace=TRUE, extension=c(".sam", ".bam"))

runCommandline(args=WF, make_bam=TRUE, dir=TRUE)
## Output paths update
WF <- output_update(WF, dir=TRUE, replace=TRUE, extension=c(".sam", ".bam"))

## End(Not run)
