[abh]

Hi,

I have 3 fastq files consisting of R1, R2 read files and
a separate index file. for example They are in the format below.

R1: @M00132:6:000000000-A0JG4:1:1:18014:1842 1:N:0:0
Sequence data

R2: @M00132:6:000000000-A0JG4:1:1:18014:1842 2:N:0:0
Sequence data

Index: @M00132:6:000000000-A0JG4:1:1:18014:1842 1:N:0:0

I want to split the R1 and R2 files based on this barcode.
and create new files that contain these barcodes

does any script or tool avaliable online so that i can work on it?
