Create pedigree plots (FamiliasPedigreeCreator)

A new tool has been developed that will create pedigree plots for all pedigrees in a specified folder. Below is a link to the software as well as getting started instructions. The software also require the software R to be installed.
FamiliasPedigreeCreator (v 1.1) - Can handle DVI and "normal" Familias projects
FamiliasPedigreeCreator (v 1.0) - Can only handle "normal" Familias projects


Users will be able to download databases prepared in the Familias (> version 3.0) in this section. Currents users are encouraged to share their Familias frequency database if possible. The allele frequencies are freely available through several online sites as well as usually available from supplementary files in papers on population data. Familias can easily import frequency data on the standard allele/marker matrix format.
From NIST 1036, we have compiled a set of databases from the 2017 revision. N represents the number of individuals.
From pop STR (see for instance Phillips et al.) we have compiled databases for 4 mayor population groups containing data for up to 70 STR markers. Details below and in previously mentioned reference.


The following files can be used to validate new versions of Familas. Results appear in this file. See also the paper Familias 3 - Extensions and new functionality

Installation instructions

The latest version of Familias will install for most Windows PC:s. For Apple users, and other OS users, a Windows environment can be simulated. In contrast to previous version (<2.0), the new Familias does not rely on .dll files and can be used as a stand-alone software, i.e. the software can be run from a USB drive. The installation should be straightforward. Should any difficulties be encountered the user are encouraged to contact Daniel Kling. (For installation instructions on the old versions, please see

English and Spanish instruction videos available here.

There has been several incidents of anti-virus software (particularly Symantec products) reporting Familias installation as a threat. This is a false alarm and has been forwarded to Symantec. Users are advised to ignore the message and run the installation anyway. If the error persists or if the installation fails, it may be that administrator rights are needed. The false alarm is caused by the fact that the new Familias is not a widely known software (even though it has quite some users), and as a new line in the defense against new threats the anti-virus software has implemented algorithms to search for "new, unknown" software/code.

Updates in Familias 3.2.8

  • Fixed some minor bugs
  • Included option in the DVI module to change the posterior model. More information will follow shortly in the updated tutorial.

Updates in Familias 3.2.7

  • Fixed a bug that caused the Create database function to crash when importing data in Genemapper format.
  • Fixed a bug that caused Familias not to save data in the DVI module
  • Fixed a bug that caused some errors when importing a frequency database from text file and then importing case DNA data.
  • Improved the allele lumping feature - activated through the Advanced dialog (will be presented at the ISFG2019 conference in Prague). It will work both for pedigrees in the normal mode as well as in the DVI module of Familias.
  • Changed the results display in the DVI module where all results will be displayed if LR=0 is chosen as threshold.

Updates in Familias 3.2.6

  • Fixed a bug when importing Genemapper data. The bug would sometimes wrongly assign incorrect alleles whenever duplicates samples were imported.

Updates in Familias 3.2.5

  • Fixed several bugs (some listed below)
    • Generate pedigree function with extra persons yielded bad results
    • Checking relations in pedigrees (DVI module) updated. Bug reported bad relations.
    • Prior computation (DVI module) updated. Results could be slightly in previous versions due to priors being computed using integers instead of floats.
    • Sorting and listing of results in the DVI module updated. Version 3.2.4 contained a bug that listed results backwards.

Updates in Familias 3.2.4

  • New allele dialog updated - It is now possible to remember choice such that all new alleles are added with the current setting.
  • Conditional simulations available - Available through the pedigrees window
  • Blind search - Minor updates to the interface. Minor allele frequency implemented in the comparisons
  • Updates in the Familial searching interface.
    • Minor bugs corrected
    • Possibility to find the maximum likelihood estimate of relationship
    • Minor allele frequency implemented in the search

Updates in Familias 3.2.2

  • Several dialogs will now display red colored text when a mismatch is detected.
    • Blind search dialog for parent/child and direct matches.
    • Merge profiles/samples dialog
    • DVI search dialog
    • Evaluate reference family
    • View reference family with DNA data and pedigree
  • When importing and displaying reference families within the DVI module, Familias will perform some elementery controls,
    • Is there at least two pedigrees defined for a specific family? If no, the family is marked with red
    • Is there at least one genotyped reference family member (data) with a relation in a pedigree? If no, the family is marker with red
    • Is there a typed reference family member with no relation in a pedigree the family is marked orange.
  • Minor updates to some windows
    • DVI search dialog displays mismatches
    • Blind search displays mismatches
  • Included the ability to change the priors in the Pedigrees dialog, warning message displayed if not sum to one.
  • New import feature for databases: Use the matrix/table format often described in publications, i.e. markers are listed in the first row, with Alleles in the first column. Identifier "Alleles" need to be present in the first cell/element of the table in order for Familias to detect the format.
  • Increased the size of some windows
  • The import of reference families in the DVI module is now more thoroughly checked. Familias will give warnings to families where some error is detected.
  • Minor changes, removed some warnings.
  • The blind search interface has been updated. Familias can now cluster matches, i.e. locate and group samples that are connected. Conditional coloring is also available.
  • The blind search interface now displays some IBS metrics.
  • Secondary sort key now works properly in the blind search dialog
  • Added support for carrige return (Enter key) in several dialogs. Default action is to close the window (without saving changes). Now some dialogs will Add new person/allele/relation when the Enter key is pressed instead.
  • Plotting a pedigree will now also generate a png file (in a Pedigree plots subfolder) that may be viewed in Familias.

Updates in Familias 3.2.1

  • The XML saving function is now improved allowing to save DVI project and files with Merged profiles.
  • Corrected some minor bugs in the DVI module
  • Improved the merging function. Now when merging profiles profiles will be displayed and the ending profile may be a combination of the two merged ones.
  • Some minor improvements to the plotting function.
  • Further corrections of some incorrectly recognized relationships in the "Import reference family" function of the DVI module.

Updates in Familias 3.2

  • Corrected some bugs detected when switching databases in Familias. Switching could cause a crash or wrong genotypes of individuals.
  • Further improvements when importing large xml databases in the familial searching module.
  • Greatly improved speed and memory handling in the blind search interface.
  • Update to the Direct-matching function in the blind search module. Dropout/Dropin/typing errors are now also considered in the denominator.
  • Information about merged profiles are now stored and can be viewed via Tools->Merged profiles. Reports may be generated as well as undoing a merge if necessary.
  • Corrected a bug that made the force minor allele frequency function not to work. For users not familiar with this feature, it allows you to force the frequencies to sum to more than 1 by using a specific MAF for each marker.
  • Exciting new feature in the DVI module: Evalute each families potential to identify a missing person (Paper in preparation). This feature allows you to perform simulation on all reference families in a DVI project to obtain all kinds of different information. We must admit, a really nice new feature.
  • Some minor bugs corrected in the DVI module.
  • Users may now run a Mendelian inheritance check on any family in the DVI module.
  • Save a project as xml (Beta). This works both as a report when LR computations have been done or use the Save as function to save the whole project. Does not work on DVI or Familial searching projects yet.
  • Greatly enhanced plotting functions, please see complete section in Manual.
  • Lumping of alleles is now allowed within the Advanced dialog. (File -> Advanced). This is currently in early Alpha testing. Briefly it allows the user to specify a threshold. This threshold applies to the probability to mutate (i.e. to observe) an allele not observed in the case data. This way even the mutation matrix for the extended stepwise model can be condensed without any bigger changes to the likelihood. We refer to future version of Familias where this feature will be explained more in detail.
