In bioinformatics, FASTA format is a text-based format for representing DNA sequences, in which base pairs are represented using a single-letter code [A,C,G,T,N] where A=Adenosine, C=Cytosine, G=Guanine, T=Thymidine and N= any of A,C,G,T.
The format also allows for sequence names and comments to precede the sequences. A sequence in FASTA format begins with a single-line identifier description, followed by lines of DNA sequence data. The identifier description line is distinguished from the sequence data by a greater-than ('>') symbol in the first column. The word following the ">" symbol is the identifier of the sequence, and the rest of the line is a description (optional) separated from the identifier by a white space or tab.
The sequence data starts on the next line following the text line and ends if another line starting with a ">" appears; this indicates the start of another sequence. Audio-Visual Tools in Science Communication: The Video Abstract in Ecology and Environmental Sciences. Introduction Science communication is usually associated to the written press format (Bentley and Kyvik, 2011) and, scientific papers continue to be the most used format in academia to disseminate the research produced (Jamali et al., 2018).
However, with the rise of the internet and the science of information technology the way science is communicated has witnessed profound changes. E-value & Bit-score - Metagenomics. E-value The BLAST E-value is the number of expected hits of similar quality (score) that could be found just by chance.
E-value of 10 means that up to 10 hits can be expected to be found just by chance, given the same size of a random database. E-value can be used as a first quality filter for the BLAST search result, to obtain only results equal to or better than the number given by the -evalue option. Blast results are sorted by E-value by default (best hit in first line). blastn -query genes.ffn -subject genome.fna -evalue 1e-10 The smaller the E-value, the better the match. NCBI DATABASES. FTP Service. Quantitative Analysis. As a Data Mining tool, Blast2GO provides various ways for the joint analysis of groups of annotated sequences.
Blast2GO generates combined graphs where the combined annotation of a group of sequences is visualized together. This can be used to study the joined biological meaning of a set of sequences. Combined graphs are a good alternative to enrichment analysis where there is no reference set to be considered or the number of involved sequences is low. This function is available under the arrow next to the "Graph'' icon. The next images show the Combined Graph Drawing Configuration Dialog, where the following parameters are available: Proteome Discoverer tutorials.

To get the most out of your workday, consider your ‘inner clock’ Ruth, a final-year Ph.D. student, is hunched over her laptop at her oversized kitchen table, typing vigorously, when her flatmate Louisa walks in.
“If you continue like this, you’ll be finished with your thesis by midnight!” Louisa exclaims. “What a pity I am not writing my thesis,” Ruth responds sheepishly. “Working on one of those papers you’ve been trying to finish?” Louisa asks hopefully. “No, I haven’t done anything like that today,” Ruth admits. Ruth knows she should write her papers and her thesis. A few weeks earlier, Ruth asked Louisa how she maintains her concentration for writing. “I don’t have my phone on, and my email is off—I still can’t concentrate,” Ruth says apologetically. This time, Louisa offers a new explanation. Ruth raises her eyebrows. “Of course not!” The previous Career Fable Career Fables are fictional stories to guide you in your real-life career journey. “Alright,” Ruth muses. “You’re right; you’re a lark. “Do you see me regurgitating owl pellets after I eat?” Functional Enrichment Analysis Tool.

If you would like to volunteer to be a reviewer, please register at Protocols are a very different format than a research article or a review, so they require a different approach to peer review. STAR Protocols includes the following unique features in its peer review process: reviewer training and certification, structured reviewer feedback, and in-line commenting.
To get the perspective of bench scientists, we may ask graduate students and post-docs to review our protocols. As this may be one of their first experiences reviewing a manuscript, we offer reviewer training and certification to help them get started. To get reviewer training and certification, please take the Elsevier Researcher Academy Certified Peer Reviewer Course. STAR Protocols aims to publish reproducible and clear step-by-step experimental procedures. Calculator for pH buffers. SPSS Nonparametric Tests Tutorials - Complete Overview.

Acid guanidinium thiocyanate-phenol-chloroform extraction. Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC) is a liquid–liquid extraction technique in biochemistry. It is widely used in molecular biology for isolating RNA (as well as DNA and protein in some cases). This method may take longer than a column-based system such as the silica-based purification, but has higher purity and the advantage of high recovery of RNA: an RNA column is typically unsuitable for purification of short (<200 nucleotides) RNA species, such as siRNA, miRNA, gRNA and tRNA.
It was originally devised by Piotr Chomczynski and Nicoletta Sacchi, who published their protocol in 1987. The reagent is sold by Sigma-Aldrich by the name TRI Reagent; by Invitrogen under the name TRIzol; by Bioline as Trisure; and by Tel-Test as STAT-60. How it works New genetic tools promise to unlock secrets of microscopic marine life. Fifty percent of the oxygen we breathe comes from ocean microbes. Yet these tiny marine organisms have largely remained a mystery to science. Now, thanks to the efforts of more than 100 researchers around the globe, scientists have found a way to unlock the genomes of a handful of these creatures by genetically engineering their DNA. The study “will propel advances in plankton biology,” says Angela Falciatore, a marine biologist with CNRS, the French national research agency, at Sorbonne University who was not involved with the work.
Those advances could shed light on the early evolution of life and potentially even lead to new antibiotics, she says. 4 simple exercises to strengthen your attention and reduce distractibility.

Seven tips to manage your mental health and well-being during the COVID-19 outbreak. I am a clinical psychologist who specializes in academic mental health and well-being. In mid-March I was due to run a resilience and well-being workshop in Sweden for doctoral candidates, but was instead facing day eight of quarantine with two small children in my apartment in Spain. Like many people’s, my sense of resilience feels increasingly frayed. When our minds are consumed by the spread of the coronavirus and its impact on our health, loved ones, home countries, economy and students — not to mention our research programme, funding or employment status, and an abrupt transition to e-learning — how do we maintain our own mental health and well-being and that of our community?
Here are some tips that have resonated from discussions I have held with academic leaders and students about responding to COVID-19: Manage your expectations.

Free online course: Training on FISH & CHIPS transcriptomic tool. AQUAEXCEL2020 is a Horizon 2020 research infrastructure project aimed at supporting the sustainable growth of the aquaculture sector in Europe through the provision of services tailored to the needs of the European aquaculture and research communities. The project offers a number of training opportunities, the latest of which is a free distance learning course covering the FISH & CHIPS tool. FISH & CHIPS is a database containing public transcriptomic data related to fish species in various physiological conditions and this bioinformatic tool can be used to extract genes which would have similar expression patterns and thus could be characteristic of fish biological responses.
The course is ideal for Early Career Researchers and others with a basic knowledge of genomics and gene expression, who want to improve their ability to analyse and interpret transcriptomic data from fish. The course consists of 4 modules and will be available through the end of September. How I learned to teach like a scientist. O que é o Arquivo.pt?
