This is a quantitative genomics summer training course (June 6 - June 11, 2020) developed by Iuliana Ionita-Laza (Columbia), Hae Kyung Im (Chicago) and Kai Wang (Penn). The topics of the course is "Methods and tools for whole-genome and transcriptome analyses".

The course is not restricted within Columbia; in fact it is open to all educational/research institutes and biopharmaceutical companies in the NYC region. However, due to COVID-19, this course was switched to be an online-only format.

In the session 1 of the first day, we discussed various computational approaches that can be used for genomic variant annotation. In the session 2, we discussed phenotype-driven prioritization of candidate genes. After lunch break, we had a hands-on exercise to analyze real-world genomic data sets using a provided VCF files with genetic variants on a patient with known phenotypic presenations.

The exercise can be reproduced from for those who registered for the course but did not have enough time to complete all exercises.



I started a bioinformatics lab in 2010. I built a computing cluster for lab members, and we have been using the cluster ever since. Occasionally some people ask me how I can admin a cluster myself, and I usually point them to the documentation on Rocks cluster. However, the documentation may be overly complicated yet insufficient to solve many of the practical problems that I encountered over the past a few years. Therefore, I decided to write a simple tutorial on building a computing cluster for a bioinformatics lab.

This tutorial is organized into several main sections:

  1. Hardware
  2. Installation
  3. System customization
  4. User account administration
  5. Network administration
  6. SGE administration
  7. Storage administration
  8. NFS administration
  9. Remote management
  10. Misc Linux configuration

The entire tutorial can be accessed at and it will be constantly updated.



This is a quantitative genomics summer training course (June 24 - June 25, 2021) developed by Iuliana Ionita-Laza (Columbia), Hae Kyung Im (Chicago) and Kai Wang (Penn). The topics of the course is "Methods and tools for whole- genome and transcriptome analyses".

This two-day intensive workshop will provide a rigorous introduction to several different techniques to analyze whole-genome sequencing and transcriptome data. Led by a team of experts in statistical genomics and bioinformatics, who have developed their own methods to analyze such data, the training will integrate seminar lectures with hands-on computer lab sessions to put concepts into practice. The training will focus on reviewing existing approaches based on predicted expression association with traits, colocalization of causal variants, and Mendelian Randomization, including discussion on how they relate to each other, and their advantages and limitations. Emphasis will also be given to reviewing integrative sequence based association studies for whole-genome sequencing data, and functional annotation of variants in noncoding regions of the genome.
