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 at each position
-doFasta 2
use the most common base. In the case of ties a random base is chosen among the bases with the same maximum 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 from a random samples of bases

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