Combine paired-end fastq files

Question

[112498262]

I am trying to use SCARPA for scaffolding. I have been given two separate paired-end fastq files, one containing each forward read and the second containing the corresponding reverse reads. SCARPA requires the read data to be in a single fastq format, whereby the forward and reverse read of each pair are consecutive in the file.

How do I merge my two fastq files to one file in the required format?

Thanks :)

That is called an interleaved fastq, so googling that should bring up some ideas.

Thank you so much. I used interleave-fastq, it worked a charm :)

Use a program from BBMap suite.

reformat.sh in1=R1.fq.gz in2=R2.fq.gz out=interleaved.fq.gz
