Reformatting BLAST+ pairwise alignment?

[lindenb]

Save your blast result as XML and process it with a XSLT stylesheet.

Examples:

* http://www.biostars.org/p/6635/

* http://www.biostars.org/p/85258/

Use a different output format (ASN, CSV, or XML). The default text-based format is only meant to be for viewing, not data manipulation, and can change without notice.

Greetings!

The default for BLAST+ output is a pairwise alignment broken up into 60bp increments:

I inquired with NCBI about a command for BLAST+ (neé StandALone BLAST) to have the aligment break at different increments or not at all. Like this:

Query  1     TTATTTTTCTTGATAGAATTAATTCTAATATTAGCACATTAAAAAATACTAAGTC-AAATTGTAATATTTCATTTGATATTGTATGCATACAATTTT-ATC---T--TACCTTTAAGAAT 113

They forwarded the request on to the development team, but don't have that functionality at the time in BLAST+. I was hoping someone might have had the same thought and wrote a little script to reformat these alignments?

Thanks!
