Moving sequence in to next line in multi fasta file

Question

[vasugautam4u]

This question might be repetitive, however I am not able to find a solution for me. I am quite new to bioinformatics I have a multi fasta file with several sequences, like this as shown below in the example. I want to move my sequence(s) in the next line after the header. I have tried couple of commands but could not get the desired output.

Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623 Lymphocytic_choriomeningitis_mammarenavirus None NP AATTTCCCCGGCCCGGG

Desired output

Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623 Lymphocytic_choriomeningitis_mammarenavirus None NP
AATTTCCCCGGCCCGGG

Any help is much appreciated.

You need to add a new line character \n explicitly. Which programming language you are using? Provide your code to answer your question perfectly.

You can try something like this; however, I would do some rigorous checking of the output.

cat test 
Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623
Lymphocytic_choriomeningitis_mammarenavirus None NP AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammar
Lymphocytic_NP AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623 hello hhhh
Lymphocytic AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammarenavirus 1653394
test ATGC

awk -F " " '!/[[:space:]][ATGC]*$/{printf $0" "}; /[[:space:]][ATGC]*$/{for (i=1; i<NF; i++) {printf $(i)" "} print "\n"$(NF)}' test

Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623 Lymphocytic_choriomeningitis_mammarenavirus None NP 
AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammar Lymphocytic_NP 
AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammarenavirus 1653394 11623 hello hhhh Lymphocytic 
AATTTCCCCGGCCCGGG
Lymphocytic_choriomeningitis_mammarenavirus 1653394 test 
ATGC

This, in its current state, will not function as expected if a sequence (ATGC) is already the only entry on any given line.
