Demultiplexing Custom Barcodes

Hey!

I am struggling to find up-to-date software for demultiplexing FASTQ files from RNA-seq data. The FASTQ files have already been demultiplexed by patient using sample barcodes, but they need to be demultiplexed a second time for different conditions. The barcodes are 25 bp long and encode five different conditions for each patient.

I was using the je-utils demultiplexing tool, but it is now outdated, and I’m wondering if anyone knows of newer tools for the same process, with better performance?

Cheers,

The barcodes are 25 bp long and encode five different conditions for each patient.

What is the location of these in the data you have? Are they consistently in-line in sequence at a certain location (front of reads?).

sabre is one potential option: https://github.com/najoshi/sabre

Thank you for your response.

I have paired-end (PE) FASTQ files, and the barcode is located in Read 1, where the sequence contains the entire barcode for a given condition. (Read 1 = 25 bp).

I will try sabre also!
