As I anticipated, I can finally release this small script. Its purpose is to build [BED files](http://http//genome.ucsc.edu/goldenPath/help/customTrack.html#BED) out of tab-delimited text files. I made this because I had several files to make and moving columns left and right (not to mention writing a heading line for the [Genome Browser](http://genome.ucsc.edu)) was becoming annoying. Its use is fairly straightforward, as the help itself says:
<!--more-->
`usage: make_bed_file.py [options] [destination]`
`options:
-h, --help show this help message and exit
-i FILE, --input=FILE
Use ranges from FILE
-n NAME, --name=NAME Use NAME as BED track name
-t TYPE, --tracks=TYPE
Format other annotation tracks according to TYPE
(default: pack)
-v TYPE, --visibility=TYPE
Set visibility of the BED track to TYPE
(default: full)
-d DISPLAY, --display=DISPLAY
Select specific annotation tracks
(comma-delimited list; default: all)`
The input file format is rather simple as well:
Chromosome | Identifier | Start Position | End position | Score
The score column is optional. The file must be tab-delimited. If you want to change the format of the file, have a look at the ncbi class inside the source. The result is a BED file with chromosome, position, name and score.
[Get the script]({{ site.url }}/files/make_bed_file.py) and make it executable. If you have any problems, please report.
