Merging VCFs in an Imperfect World

         September 7, 2021

Merging variant records across samples is important when performing trio or family analysis as it ensures that hereditary relationships can be properly inferred. There are many ways to represent a single variant. Insertions and deletions may be right or left aligned, prefixes and suffixes can be added, and adjacent variants in the same sample may be combined or split at… Read more »

Auto-Updating Template Sources

ClinVar

In VarSeq 2.2.1, you can set template annotation sources to automatically update to the latest version. Previously, VarSeq templates were frozen in time. Now, each new project created from a template would use the same source that was used when the template was created. When you save a template, you can have the sources automatically update to the latest version…. Read more »

Automating Clinical Workflows: Part III

         April 19, 2019

In the previous two articles, we explored the different steps of a clinical workflow. The first post covered the automated analysis that creates a VarSeq project. While the second post covered the interpretation steps and generation of a clinical report. These posts illustrated the ease with which these complex tasks can be carried out. Today we’ll dig a little bit… Read more »

Automating Clinical Workflows: Part II

         April 11, 2019

In the previous blog post, we covered the automated steps to create a VarSeq project. Today we will examine the active analysis steps. These are the steps that require human interpretation to analyze the clinically relevant variants. A lab tech can take the first pass at the output in the generated VarSeq project. They can perform the quality control and… Read more »

Automating Clinical Workflows: Part I

         April 3, 2019

Automating a clinical workflow creates a stable and repeatable clinical analysis. Automation reduces the potential to introduce human error, helps in regulatory compliance, and improves the precision of the clinical results. It is important to know that if you run a sample through your clinical pipeline, you are going to get the same results today as you will in 6… Read more »

VSPipeline Tips and Tricks

VSPipeline Tips & Tricks

The power of VSPipeline is in it’s ability to automate VarSeq workflows. Using VarSeq to create a pipeline template is great because it allows you to dial in the applied filters as well as interactively organize the annotations and applied algorithms. Automating a workflow with VSPipeline is  straightforward when beginning with an existing project. However, there are several steps that… Read more »

Quality Assurance Sample Statistics Added To VarSeq

         February 18, 2016
VarSeq

As VarSeq continues its adoption amongst clinical labs and researchers looking for reproducible workflows for variant annotation, filtering and interpretation, we have continued to prioritize the addition of features to assess the quality of the upstream data at a variant, coverage and now sample level. The  Importance of Quality Assurance Sample prep and sequencing problems are difficult to detect through the analysis… Read more »
