    convert vcf to hapmap

    I was trying to use SNPhylo software.
    I needed to combine multiple SNP vcf files together or use combined hapmap file.
    Is there any way to get single vcf or hapmap file with multiple samples together?

          I fed SNPhylo only a VCF file and it ran smoothly. If you use SNPhylo, please check the sam headers, it seems SNPhylo only accept number as chromosome header (e.g. >1 but not >chr1) at least for old SNPhylo version (2014.....). Hope it helps.

            SNPhylo

            hi yzzhang, i appreciate your help. I have this project to find SNPs across 5 different population and build a phylogenetic tree. so, for my VCF file should i combine all the SNPs from all population into one VCf file and then run SNPhylo??

              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.
