Welcome @aaku7
Would this tool combination work for you as an alternative?
- Format Fastq sequences and barcode data (extract_barcodes) (link at the UseGalaxy.eu server)
- Split libraries according to barcodes specified in mapping file (link at the UseGalaxy.eu server)
Then search the tool panel for the other tools – the EU server and most of the other UseGalaxy servers have these, plus the intermediates tools you’ll likely want.
Be sure to scroll down on tool forms to see a short Help guide and link-outs to how the original tools are used, plus 
GTN Tutorials https://training.galaxyproject.org/ (if that tool happens to be included in one – you can also search the site directly by Categories/Domain).
If you are currently working at a different Galaxy server – contacting the administrators directly is how to request tools. Please let us know the URL if you cannot find the contact and we can try to help.
And, a reminder that you can move data between servers if you need to – all by URL. Many have large self-serve extended quota options.
