How to add line breaks before each ">" header line in fasta file
Hello, I have a big fasta file with hundreds of sequences. In some cases the fasta sequences do not have line breaks between them. I would like to add a line break before each header.
For example, right now it looks like this:
">name ATCGCTGCGAT>name2 ATATCGTGA"
And I want it to look like this:
">name ATCGCTGCGAT"
">name2 ATATCGTGA"
Thank you for any help!
