loadWorkflow {systemPipeR} | R Documentation |
The constructor functions create an SYSargs2
S4 class object from three input files: a CWL param
and input
files, and one simple tabular files, a targets
file. The latter is optional for workflow steps lacking input files. TheCWL param
provides all the parameters required for running command-line software, following the standard and specification defined on Common Workflow Language (CWL). The input
file provides additional information for the command-line, allowing each sample level input/outfile operation uses its own SYSargs2
instance. In the targets
file users could provide the paths to the initial sample input files (e.g. FASTQ) along with sample labels, and if appropriate biological replicate and contrast information for controlling differential abundance analyses.
