Porechop: tool for finding and removing adapters from Oxford Nanopore reads

Rahul Nayak — Tue, 29 May 2018 07:33:44 -0500

Porechop is a tool for finding and removing adapters from Oxford Nanopore reads. Adapters on the ends of reads are trimmed off, and when a read has an adapter in its middle, it is treated as chimeric and chopped into separate reads. Porechop performs thorough alignments to effectively find adapters, even at low sequence identity.

Porechop also supports demultiplexing of Nanopore reads that were barcoded with the Native Barcoding Kit, PCR Barcoding Kit or Rapid Barcoding Kit.

EMBO practical Course on "Bioinformatics and Genomes Analyses" at Hellenic Pasteur Institute, Athens, Greece

Sat, 21 Dec 2013 10:00:24 -0600

The main objectives of this Practical Course are to strengthen skills
of PhD students and young researchers in the domain of Bioinformatics
and Genome Data Analyses on the use of advanced fundamental algorithms
and their applications in genome studies.

The course topics will include theoretical and practical aspects in:
- Genomes comparisons,
- Evolutionary analyses (orthologs, paralogs and ancestral genomes
inference),
- RNAseq and Next Generation Sequencing (including algorithms, methods
and sequence mapping tools, data analyses and applications).

The course programme will be centred on theoretical presentations
followed by practical sessions. Practical sessions in a Linux
environment will involve Unix shell and Perl scripting. Participants
are assumed to be familiar with this environment.

A series of lectures delivered by prominent scientists on recent hot
topics in genome (Viruses, Prokaryotes, Eukaryotes) studies will be
included in the programme and future research perspectives will be
highlighted.

The topics that will be included in the course programme are similar
to those included in previously organized courses:http://www.pasteur.fr/~tekaia/BGA_courses.html

The course is aimed at motivated Ph.D students and Post-Doctoral
Researchers in Academic Institutions, with background in Mathematics,
Statistics, Biology or Computer Science and who are involved in
Bioinformatics and Genomes studies.

Selection of participants will be based on their background, running
research projects and on expressed motivations.
Selected students will have free accommodation and meals and are
expected to contribute with 200 euros and to pay for their travel
expenses.
All participants (students and invited speakers) will stay in the same
hotel.

List of non-commercial NGS genotype-calling software

Jit — Thu, 09 Aug 2018 04:21:32 -0500

Meaningful analysis of next-generation sequencing (NGS) data, which are produced extensively by genetics and genomics studies, relies crucially on the accurate calling of SNPs and genotypes. Recently developed statistical methods both improve and quantify the considerable uncertainty associated with genotype calling, and will especially benefit the growing number of studies using low- to medium-coverage data.

Oldest Hominin DNA Sequenced

Surajeet — Fri, 27 Dec 2013 19:58:31 -0600

Matthias Meyer and his team from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have developed new techniques for retrieving and sequencing highly degraded ancient DNA. They then joined forces with Juan-Luis Arsuaga and applied the new techniques to a cave bear from the Sima de los Huesos site. After this success, the researchers sampled two grams of bone powder from a hominin thigh bone from the cave. They extracted its DNA and sequenced the genome of the mitochondria or mtDNA, a small part of the genome that is passed down along the maternal line and occurs in many copies per cell. The researchers then compared this ancient mitochondrial DNA with Neandertals, Denisovans, present-day humans, and apes.

From the missing mutations in the old DNA sequences the researchers calculated that the Sima hominin lived about 400,000 years ago. They also found that it shared a common ancestor with the Denisovans, an extinct archaic group from Asia related to the Neandertals, about 700,000 years ago. "The fact that the mtDNA of the Sima de los Huesos hominin shares a common ancestor with Denisovan rather than Neandertal mtDNAs is unexpected since its skeletal remains carry Neandertal-derived features," says Matthias Meyer. Considering their age and Neandertal-like features, the Sima hominins were likely related to the population ancestral to both Neandertals and Denisovans. Another possibility is that gene flow from yet another group of hominins brought the Denisova-like mtDNA into the Sima hominins or their ancestors.

The 2014 CeMM PhD Program

Wed, 05 Feb 2014 06:03:15 -0600

For our next PhD Program starting in October 2014 we are looking for exceptionally motivated PhD candidates with a keen interest in genomics and medicine and a strong interest to work in teams.

The 2014 CeMM PhD Program will focus on two thematic areas: INFECTION and CANCER, that are built on the pillars of epigenetics, bioinformatics and systems biology, chemical biology and the mechanism of action of drugs, high-throughput genetics, genomics and proteomics, and molecular and cell biology.

The choice of this strategic focus rests on the synergies between immunology, infection and cancer in pathophysiological and technological terms. It furthermore reflects the strength of the current CeMM faculty, itself built around the historical and contemporary expertise in immunology and cancer of the Medical University of Vienna.

As a CeMM PhD student you will get the chance to work at the cutting edge of interdisciplinary molecular medicine research and be trained by the entire CeMM and associated faculty to become one of the scientists shaping the future of molecular medicine.
Requirements

To be eligible to enroll in the CeMM PhD Program all candidates are required to have a bachelor’s or master’s degree in medicine, biology, chemistry, bioinformatics, mathematics or any scientific/technical, subject-relevant degree. Candidates do not need to have completed their degree at the time of application, however they must have obtained their final degree certificate by mid-September. The working language at CeMM is English, so excellent written and oral communication skills in English are required.
Timeline

Applications open on 20th January and close on 20th March 2014.
Two references are required to be submitted through the online system by 31st March 2014.
All complete candidate applications are reviewed by the CeMM Faculty in early April.
Selected candidates are invited to a Skype panel interview in late April.
Shortlisted candidates are then invited to Vienna in May for a full interview process, including an opportunity to introduce yourself through a presentation and interview rounds, meet research group members, and attend an informal dinner to get to know the Faculty members and learn more about their research.
Positions are offered by CeMM Faculty in June.
Start of PhD Program: 1st October 2014 .
