37 **What it Does**
|
|
|
38
|
|
|
39 Performs merging of paired reads.
|
|
|
40
|
|
|
41 The FASTQ filename for the forward reads is specified by the -fastq_mergepairs option, and the reverse read filename is specified by the -reverse option. Output files are specified by -fastqout (for FASTQ) and / or -fastaout (for FASTA).
|
|
|
42
|
|
|
43 Forward and reverse must be in 1:1 correspondence and must appear in the same order in both files. The labels for the forward and reverse read in a given pair must be identical except for a single position where a '1' appears in the forward read label and a '2' appears in the reverse read label.
