Examples

# Create an empty `.fastq` file for patient ID "Patient_001" and
#  sample ID "SMP_001"
 create_empty_fastq("Patient_001", "SMP_001")
#> Empty `.fastq` file created at: /tmp/RtmpQD3okl/Patient_001_SMP_001.fastq
# Inside a specific directory, Create an empty `.fastq` file for
# patient ID "Patient_001" and sample ID "SMP_002"
 create_empty_fastq("Patient_001", "SMP_002", output_dir = tempdir())
#> Empty `.fastq` file created at: /tmp/RtmpQD3okl/Patient_001_SMP_002.fastq
