Python vcf

Small library for parsing vcf files. Based on PyVCF. Vcf parser is really a lightweight version of PyVCF with most of it's code borrowed and modified from there. The idea was to make a faster and more flexible tool that mostly work with python dictionaries. It is easy to access information for each variant, edit the information and edit the headers. Returns dictionary with the vcf info for each variant. INFO field is parsed into a dictionary The keys are the names of the info field and values are lists separated on ','. A vcf file must allways have the "fileformat" header, so start by initializing a vcf parser with the name of the fileformat like. Where 'number', 'type' and 'description' follows the VCF specification. Skip to content. You signed in with another tab or window. Reload to refresh your session.

A description of each key should be given in the meta-information section as described above. Apr 23,

I've been using PyVCF with quite some success in the past. However, the main bottleneck of PyVCF is when you want to modify the per-sample genotype information.

I've been using PyVCF with quite some success in the past. However, the main bottleneck of PyVCF is when you want to modify the per-sample genotype information. There are some issues in the tracker of PyVCF but none of them can really be considered solved. I tried several hours to solve these problems within PyVCF but this never got far or towards a complete rewrite VCFPy is the result of two full days of development plus some maintenance work later now right now. I'm using it in several projects but it is not as battle-tested as PyVCF. As I'm only using Python 3 code, I see no advantage in carrying around support for legacy Python 2 and maintaining it. At a later point when VCFPy is known to be stable, Python 2 support might be added if someone contributes a pull request. Skip to content.

If these lines are missing or incomplete, it will check against the reserved types mentioned in the spec. Failing that, it will just return strings. There main interface is the class: Reader. It takes a file-like object and acts as a reader:. This produces a great deal of information, but it is conveniently accessed. The attributes of a Record are the 8 fixed fields from the VCF spec:. The format of the fixed fields is from the spec.

Note however that for the case of Medaka this interpretation should be taken with a pinch of salt, the scores output by the Medaka neural network have not been empirically calibrated to error rates of calls.

Let's try to index a gzip -compressed file to observe what happens:. Not withstanding this fact we will now look at a second method for parsing VCF files in Python. We will come back to index file later in the tutorial. Medaka will output a ". In particular, one-entry VCF lists are converted to one-entry Python lists see, e.
