Ensuring to find the correct file after Demultiplexing my 16S amplicon raw dataset with combinatorial dual indexes cutadapt command

• Cutadapt and Python version used: 4.8
• The method you used to install the tool (conda or pip, for example): Used mamba
• The command-line parameters you used for demultiplexing paired-end reads with combinatorial dual indexes cutadapt command:

cutadapt \
    -e 0.15 --no-indels \
    -g ^file:barcodes_fwd.fasta \
    -G ^file:barcodes_rev.fasta \
    -o {name1}-{name2}.1.fastq.gz -p {name1}-{name2}.2.fastq.gz \
    input.1.fastq.gz input.2.fastq.gz

Here are some of the output generated from the code above:

LIB1_sample_189-LIB1_sample_183.1.fastq.gz
LIB1_sample_189-LIB1_sample_183.2.fastq.gz
LIB1_sample_189-LIB1_sample_184.1.fastq.gz
LIB1_sample_189-LIB1_sample_184.2.fastq.gz
LIB1_sample_189-LIB1_sample_185.1.fastq.gz
LIB1_sample_189-LIB1_sample_185.2.fastq.gz
LIB1_sample_189-LIB1_sample_186.1.fastq.gz
LIB1_sample_189-LIB1_sample_186.2.fastq.gz
LIB1_sample_189-LIB1_sample_187.1.fastq.gz
LIB1_sample_189-LIB1_sample_187.2.fastq.gz
LIB1_sample_189-LIB1_sample_188.1.fastq.gz
LIB1_sample_189-LIB1_sample_188.2.fastq.gz
LIB1_sample_189-LIB1_sample_189.1.fastq.gz
LIB1_sample_189-LIB1_sample_189.2.fastq.gz
LIB1_sample_189-LIB1_sample_190.1.fastq.gz
LIB1_sample_189-LIB1_sample_190.2.fastq.gz

1. What is the correct combination of fastq.gz files for further analysis? I have a total of 230 samples.
2. How can I pick those right files from the combination pool folder?

Start with Cutadapt's documentation for demultiplexing paired-end reads and combinatorial dual indexes, then reproduce the supplied command on a small input subset. Compare the generated paired filenames with the barcode combinations and document how valid pairs can be identified and selected for all samples.
