Extract reference and aligned sequences from BAM file basing on VCF file

[floem7]

Thanks, I've followed example found at vcftools page and it works :-)

Great thanks!

Edit: however, I realized that aligned fasta format would be better. The aim is to quickly generate
friendly msa view for a given region. For example for primer design.

Certainly, ordinary MSA programs don't create sufficiently similar alignment as this in bam file.
So it require manual inspection.

Forgot to mention, if you just want to extract FASTA sequences for GFF features (i.e. without any called variants applied), you can use BEDTools getfasta (http://bedtools.readthedocs.org/en/l.../getfasta.html).

You can try

- "vcf-consensus" from VCFtools: http://vcftools.sourceforge.net/perl...#vcf-consensus. Click on "Read more" to get an example how to get the consensus for a given region within the reference sequence (you need to extract this information from your GFF).

or

- FastaAlternateReferenceMaker within GATK (https://www.broadinstitute.org/gatk/...renceMaker.php)

Read the documentation thoroughly - there are several caveats!

I couldn't find relevant information. I hope it's not duplicate.

I have resequencing data for two maize lines (BAM and VCF files).
I want to extract sequences (fasta) for several genes (I have also GFF3 file with annotation data) from reference genome and corresponding sequences from resequencing data. I probably could use sequence identifiers, as they are in my files

Which tool allows to extract such data, and more generally to extract sequences for
a given variant type (SNP, indel, etc) and location (exon, intron, etc)?
