Hello, I got paired end sequences with different sample number and lane number (showing one sample fastq files below) .

1) D3M0_S1_L001_R1_001.fastq.gz 2) D3M0_S45_L002_R1_001.fastq.gz

3) D3M0_S1_L001_R2_001.fastq.gz 4) D3M0_S45_L002_R2_001.fastq.gz

Should i Merge S1 and S45 using cat ? or should i perform seperately each S1 and S45 and get individual read count data ?

what is the better approach for downstream analysis of RNAseq analysis?

if i need to merge , what is the better approach ?

Are they the same sample? If they are both actually the same sample then I would merge, otherwise treat them as replicates.

It is odd that you have two different S* numbers of the same sample in different lanes. Generally one should have the same S* for the same sample in different lanes.

But to answer your question, if it is the same sample then you can cat the two files together.

perhaps the sample sheet provided to the converter listed these as separate samples.
