Insert new line help

So I have a file that contains

Code:

>NM_#########AUGCAUCGUAGCUAGUCGAUACUGGACUG>NM_########AUGAGUAUGUAUGAUGUAUGUAUGA

where # is any digit 0-9 (the text is many repetitions of the pattern above, not just that, but all in one line), and I want it to show

Code:

>NM_#########

AUGUAGUGCUAGCUGAUCGAUGCUAGUCGUAGC

>NM_########

AGUGAGUCGUCGUGACUGACUGUGGCAUCGUA

Basically I need to add a new line before every > and between a number and a letter.

OR

If it's easier, I have something like this

Code:

>NM_#########

AUGCUGAC

GACGUAGC

ACGUGUAG

>NM_########

AGUGCUGA

ACGUAGCU

ACGUGCUA

and I want to condense all the letter only lines to one line, like the output shown above.

If someone could help me how to do this with a simple command, it would really help.

Thank you!

Have a look at this:

Code:

$ echo '>NM_12345AUGCAUCGUAGCUAGUCGAUACUGGACUG>NM_987654321AUGAGUAUGUAUGAUGUAUGUAUGA' | \

sed -r 's/>NM_([0-9]+)/\n>NM_\1\n/g'



>NM_12345

AUGCAUCGUAGCUAGUCGAUACUGGACUG

>NM_987654321

AUGAGUAUGUAUGAUGUAUGUAUGA

Code:

$ sed -r 's/[AUGCT]+/\n&\n/g' file

>NM_7675435267

AUGCAUCGUAGCUAGUCGAUACUGGACUG

>NM_76532650

AUGAGUAUGUAUGAUGUAUGUAUGA



$

with an extra newline at the end.

@colucix: Nice.

And if this has to do with DNA/RNA codons then yours might be preferable, I am assuming That the NM_ part is static.....
