# Label Non-Labeled Outputs

**Available from:** Clarity LIMS v2.0.5

A user may need to add reagent labels to sample outputs that do not have reagent labels assigned to them.

## Script Overview

The *labelNonLabeledOutputs* script provides the ability to add reagent labels to sample outputs for which there is no pre-existing reagent label.

The script checks each process output for existing reagent labels; if an output does not have at least one pre-existing reagent label then the label supplied as a script parameter is applied.

* For each output that does not already have a reagent label applied to it (e.g. control samples), the script will apply a reagent label named with the supplied string.
* In the Preconfigured Package for Illumina NGS, all sequencing libraries go through a demultiplex process to both convert data to FASTQ and demultiplex reads if necessary. Note that presently, inputs that do not have a reagent label do not create an output in a demultiplex process even though we need BCL convertor to convert their reads to FASTQ.
