Haploid calling

Simple haploid output based on sampling or consensus. Major bug in version 0.911 (not in <0.911). Use the developmental version github

--------------
abcHaploCall.cpp:
	-doHaploCall	0
	(Sampling strategies)
	 0:	 no haploid calling 
	 1:	 (Sample single base)
	 2:	 (Concensus base)
	-doCounts	0	Must choose -doCount 1
Optional
	-minMinor	0	Minimum observed minor alleles
	-maxMis	-1	Maximum missing bases (per site)

This function outputs a base for each individual for each site

Options

-doHaploCall [int]

1; sample a random base 2; most frequent base. Random base for ties

-doCounts 1

use -doCounts 1 in order to count the bases at each sites after filters.

-minMinor [int]

Minimum observed minor alleles; only prints sites with more than minMinor sampled alleles (across individuals).

-maxMis [int]

maximum allowed missing alleles (accross individuals). -maxMis 0 means only sites without missing alleles are printed

Output

• .haplo.gz

Output: Each line represents site. chromsome name (Column 1), position (Column 2), major allele (Column 3). One column for each individual with the sampled allele.

Example

Create a fasta file bases from a random samples of bases.

./angsd -bam bam.filelist -dohaplocall 1 -doCounts 1 -r 1: -minMinor 1
