Back to Basics: Importing/Exporting Data in Imputation Program Data Formats with SVS

In a recent blog post (Comparing BEAGLE, IMPUTE2, and Minimac Imputation Methods for Accuracy, Computation Time, and Memory Usage), Autumn Laughbaum compared three imputation programs. Data can be exported from, or imported into, SVS in the standard file formats for these and other imputation programs. The goal of this blog…

Follow Along on an Analyst’s Journey to Filter Whole Genome Data to Four Candidate Variants in SVS

Last week Khanh-Nhat Tran-Viet, Manager/Research Analyst II at Duke University, presented the webcast: Insights: Identification of Candidate Variants using Exome Data in Ophthalmic Genetics. (That link has the recording if you are interested in viewing.) In it, Khanh-Nhat highlighted tools available in SVS that might be under used or were…

Dr. Ken Kaufman’s Webcast on Exome Sequencing Wildly Successful

Thank you to everyone who joined us yesterday for a webcast by Dr. Ken Kaufman of Cincinnati Children’s Hospital: “Identification of Candidate Functional Polymorphism Using Trio Family Whole Exome DNA Data.” Over 750 people registered for this event and 430 attended – a new Golden Helix record! If you missed…

Why You Should Care About Segmental Duplications

My work in the GHI analytical services department gives me the opportunity to handle data from a variety of sources. I have learned over time that every genotyping platform has its own personality. Every time we get data from a new chip, I tend to learn something new about the…

Analyzing PacBio Data with SNP & Variation Suite

As most in the Golden Helix community are aware, SNP & Variation Suite (SVS) can handle all sorts of data including files from Affymetrix, Illumina, Agilent, and Complete Genomics with its powerful data management capabilities. Announced in February, SVS is now part of the Pacific Biosciences Partner Program and has…

Sequence Analysis Methods Not Just for Sequence Data

Speaking as somebody with a long history in data analysis, there are few things I find more exciting and tantalizing than new analysis methods that might apply to a problem I am trying to solve or was unable to solve in the past. Whenever I make a breakthrough in one…

Marker Map Manipulation Improvements in SVS 7.5

Manipulating a marker map in SVS has never been easier, thanks to expanded functionality in SVS 7.5. Have you ever wanted to view annotation data next to marker map data? Or expand the current marker map with spreadsheet data to create a custom map? SVS 7.5 features two new functions…

Please Help Me Get My Regression Model Set Up!

Golden Helix’ SNP & Variation Suite (SVS) has a Regression Module to enable researchers with varying degrees of statistical knowledge to interrogate their data using regression models to account for potential confounding effects of covariates and interaction terms. While these tools are labeled “basic”, they can be difficult to use…

CNV Analysis Tips for Illumina Data

Please see our updated tutorials for CNV Analysis by visiting: https://www.goldenhelix.com/resources/SNP_Variation/tutorials/index.html The following statement is representative of a common question that is posed to the Golden Helix support team: “I followed all of the steps in the SVS7 CNV analysis tutorial, but my results seem kinda funny. The segment means…
