join_seq joins sequences in the stream. This is done by locating all records with a SEQ key and concatenate the
values of these into a new record with REC_TYPE: JOIN. The SEQ_NAME of this record is the first SEQ_NAME encountered
(if encountered).
... | join_seq [options]
[-? | --help] # Print full usage description.
[-d <string> | --delimiter=<string>] # Delimiter used for joining sequences - Default=""
[-I <file!> | --stream_in=<file!>] # Read input from stream file - Default=STDIN
[-O <file> | --stream_out=<file>] # Write output to stream file - Default=STDOUT
[-v | --verbose] # Verbose output.
Consider the following sequence entries in FASTA format in the file test.fna:
>test1
aaaa
>test2
tttt
>test3
cccc
>test4
gggg
To join the sequences use read_fasta:
read_fasta -i test.fna | join_seq
SEQ_NAME: test1
SEQ: aaaa
SEQ_LEN: 4
---
SEQ_NAME: test2
SEQ: tttt
SEQ_LEN: 4
---
SEQ_NAME: test3
SEQ: cccc
SEQ_LEN: 4
---
SEQ_NAME: test4
SEQ: gggg
SEQ_LEN: 4
---
SEQ_NAME: test1
SEQ: aaaattttccccgggg
SEQ_LEN: 16
REC_TYPE: JOIN
---
To use a different delimiter use the -d switch:
read_fasta -i test.fna | join_seq -d X
SEQ_NAME: test1
SEQ: aaaa
SEQ_LEN: 4
---
SEQ_NAME: test2
SEQ: tttt
SEQ_LEN: 4
---
SEQ_NAME: test3
SEQ: cccc
SEQ_LEN: 4
---
SEQ_NAME: test4
SEQ: gggg
SEQ_LEN: 4
---
SEQ_NAME: test1
SEQ: aaaaXttttXccccXgggg
SEQ_LEN: 19
REC_TYPE: JOIN
