You can try an online sequence converter like http://www.ebi.ac.uk/Tools/sfc/readseq/

For example, the Genbank format will give you the output you want.

I use macro in the TextPad (http://www.textpad.com/). Is a very good text editor for edit DNA sequencies.

You can use fold command in linux and create a file which you can easily view in MSword. for example:

fold -w 10 seq_input_file.fa > newfile_10blocks.fa

-w sets the character limit to 10 here.

Hi Zahra

Use free sequence format converters as suggested above...they will be convenient

Thank you Ricardo, Margarida and Shabhonam.

I used http://www.ebi.ac.uk/Tools/sfc/readseq/ and it worked.

If you want to do it specifically in MS Word in the future, you can search for:

^$^$^$^$^$^$^$^$^$^$

to search for a string of any ten letters, or turn wildcards on and search for

[acgtnACGTN]{10}

to search for a,c,g,t,n,A,C,G,T,N occuring in sets of 10, and replace with

^&

with a space after the "^&" to replace with the same pattern, with a space at the end. This won't give you the line numbers etc that some other sequence formats will be giving you though. You could replace with ^&^l to get the blocks of 10 all on different lines, if that's what you meant.

The word-addin "Molecular BioComputing Suite" (MBCS.dot) should do the job too (not sure if it works still with office 2013).

I wrote an R package that does this:
