See https://www.biostars.org/p/7290/ Question: Tools Parsing Ncbi Blast -M 7 Xml Output Format?

**SDPA_Pet** · 07-31-2014, 07:28 AM

Any other tools with GUI version? I am not familiar with perl

**maubp** · 07-31-2014, 12:54 PM

Here's my Python script https://github.com/peterjc/galaxy_bl..._to_tabular.py with Galaxy wrapper https://github.com/peterjc/galaxy_bl...to_tabular.xml - does that count as a GUI?

Hi thanks. I download your scripts and save it as blastxml_to_tabular.py. How should I use it.

should I type python blastxml_to_tabular.py -i nitrogen.xml -o nitrogen.txt.

I am sorry about this kind of newbie questions. I am a biological student. I don't have any background of computer sciences.

I attached the blastxml_to_tabular.py. Please have a quick look and see the format is correct or not.

It looks like you got the Galaxy XML file by mistake. This https://github.com/peterjc/galaxy_bl..._to_tabular.py is the pretty Human Readable page for the Python script, this https://raw.githubusercontent.com/pe..._to_tabular.py link will download the script itself ready to run.

Are you using Linux, Mac OS X, or Windows? If Windows you will also need to install Python and running it is a little more complicated. Linux and the Mac should already have a suitable version of Python installed.

**SDPA_Pet** · 08-01-2014, 07:08 AM

I tried on windows but it says some errors.

Can you give me an example of using this script, if I want to convert 12 column txt file.

**maubp** · 08-01-2014, 07:14 AM

What errors? If you copy/paste the message here it would be far easier to guide you - but I guess part of the problem is you are using -i which is not expected.

Assuming you installed Python 2.7, you would run something like this - the default is the standard 12 column output:

Code:

C:\Python27\python blastxml_to_tabular.py -o nitrogen.txt nitrogen.xml

**SDPA_Pet** · 08-01-2014, 07:25 AM

Hi, I want to convert xml to txt?

should it be python blastxml_to_tabular.py nitrogen.xml -o nitrogen.txt

do I need to type an "-i" in front of "nitrogen.xml"

The error is invalid data format

**maubp** · 08-01-2014, 07:38 AM

In this case, either is fine:

Code:

python blastxml_to_tabular.py -o nitrogen.txt nitrogen.xml

Code:

python blastxml_to_tabular.py nitrogen.xml -o nitrogen.txt

Note that in general many command line tools are fussy about the exact order.

What does your file "nitrogen.xml" look like? Can you share it via http://gist.github.com or perhaps show the first ten lines here inside [ code ] and [ /code ] tags?

(The code tags are available via the forum's advanced editor view using the "#" icon.)

I have the original file but it didn't work either. Here it is

That file is also just plain text BLAST output.

**SDPA_Pet** · 08-01-2014, 07:56 AM

Oh, when I did the blast I use -m 7 and it says it is xml format. Is there any software to convert this to tabular format? I used the old BLAST not BLAST+
