    vcftools typical usage

    Hi all,
    I've noticed that vcftools exist... seriously, if you search "vcftools" in seqanswer forum you'll find only 3 threads. BTW I don't want to start a flame about this :-)
    I just wonder if anybody here has some experience of these tools and wants to share some usage tips and typical scenarios. vcftools binary comes with many options, and so do the perl scripts. The vcftools pages apparently have no wiki pages (such the samtools or GATK ones)...

    All I've used it for

    Code:
    vcftools --vcf some1000genomesFile.genotypes.vcf --counts --minDP 3
    will give you something like:
    Code:
    CHROM	POS	N_ALLELES	N_CHR	{ALLELE:COUNT}
    1	533	2	92	G:87	C:5
    1	41342	2	54	T:38	A:16
    1	41791	2	62	G:58	A:4
    1	44449	2	50	T:48	C:2
    1	44539	2	36	C:35	T:1
    Code:
    awk '{print "chr"$1"\t"$2-1"\t"$2"\t"$5"\t"$6}'
    and you have a bed file of 1000 genomes variants:
    Code:
    chr1	532	533	G:87	C:5
    chr1	41341	41342	T:38	A:16
    chr1	41790	41791	G:58	A:4
    chr1	44448	44449	T:48	C:2

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by SEQadmin2


      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

      Here are nine questions we think about, in roughly the order they matter, before...

      From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
      by SEQadmin2


      Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


      The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
