Fasta

This option create a fasta file from a sequencing data file. The function uses genome information in the bam header to determing the length and chromosome names. For the sites without data an "N" is written.

Brief Overview

> ./angsd -doFasta
--------------
analysisFasta.cpp:
	-doFasta	0
	1: use a random base
	2: use the most common base (needs -doCounts 1)
	-minQ		13	(remove bases with qscore<minQ)

options

-doFasta 1

sample a random base

-doFasta 2

use the most common base. In the case of ties a random base is chosen among the bases with the same counts. The "-doCounts 1" options for allele counts is needed in order to determine the most common base

-minQ [INT]

minimum base quality score

Example

Create a fasta file bases on a random samples of bases

./angsd -i smallNA07056.mapped.ILLUMINA.bwa.CEU.low_coverage.20111114.bam -doFasta 1
