== NOTE ==
If you are interested in calling '''''de novo''''' mutations in '''trios''' based on '''VCF''' files, we recommend our new tool, triodenovo, which implemented a nicer algorithm with a more natural interpretation of the ''''''de novo''''' quality. Please check it out following the link below. Thanks for trying it out!

The latest version of 0.15 is available for [[#Download | Download]].
The latest version of 0.18 is available for [[#Download | Download]].
v0.18 fixed a bug when it reported inbreeding for some pedigrees which are not inbreeding families
v0.17 fixed a bug when some of the samples in the per files are not in the input vcf file
v0.16 fixed a bug when the input is a VCF file with multiple nuclear families and the ped file contains only a single nuclear family.
v0.15 added an option (--mixed_vcf_records) to handle input vcf files in which mixed records with different FORMAT fields are present.

v0.14 implemented both inherited variant calling and de novo mutation detection from VCF input files. If you have a VCF file with PL or GL fields, you can run polymutt on the VCF file to quickly and conveniently call variants and mutations.

*NOTE: When there is missing data in a trio or family in VCF files, the de novo calling is not reliable and often times is not possible. So these sites should be ignored for de novo mutations.

v0.13 fixed the bug for generating genotypes when the input is a VCF file and the ped file contains only a single nuclear family. Like unrelated samples (e.g. [[http://gatkforums.broadinstitute.org/discussion/1186/best-practice-variant-detection-with-the-gatk-v4-for-release-2-0 GATK]] recommends at least 30 samples), it is also desirable to use more families or mixture of families and unrelated samples for polymutt.
