I’m looking to filter reads that contain a stretch of A’s, I found these posts looking for polyA tails, meaning this should work all the same (Identify RNA-seq reads containing polyA sequence, Identifying RNA-seq reads containing polyA stretch). However, I cannot get it to work. Given just these two reads,…

circRNA quantification, differential expression analysis and miRNA target prediction of RNA-Seq data Introduction nf-core/circrna is a best-practice analysis pipeline for the quantification, miRNA target prediction and differential expression analysis of circular RNAs in paired-end RNA sequencing data. The pipeline is built using Nextflow, a workflow tool to run tasks across…

Although the hypothesis of gene-regulatory network (GRN) cooption is a plausible model to explain the origin of morphological novelties (1), there has been limited empirical evidence to show that this mechanism led to the origin of any novel trait. Several hypotheses have been proposed for the origin of butterfly eyespots,…

So my question comes in two parts: First of all is what I’m trying to do within reason given the tools I am using? I am investigating the shuffling effects of a recombinase on a known reporter sequence which subsequently generates libraries of unique sequences. By simulating all of the…

#How to map to the assembled scaffolds.fasta bbmap is a powerful and highly flexible read mapper jgi.doe.gov/data-and-tools/bbtools/bb-tools-user-guide/bbmap-guide/. For the upcoming analysis you are not interested in the typical mapping output but in statistics on the coverage on every scaffold, you can get them with scaffstats. We want to be specific…

RNA-seq analysis cloud server 1 Hi all, I have some RNA-seq of mice (around 200GB) and I want to perform a RNA-seq analysis (including QC, mapping, quantification, differential expression analysis). But I don’t know how to choose a server. Could anyone can tell me to process such a dataset, how…

is BBMap/Qualimap affected by log4j vulnerability 2 no, unless the tools are used as a library in a web server. It’s worth noting picard.jar and abra.jar are affected (even though as Pierre L says, these are unlikely to be attacked on most systems). If you’re responsible for systems, esp web…

Average Read length 3 Hello Everyone! Is there a standard tool commonly used to calculate the average read length of fastq files? If yes please mention it here because I want to know the size of average reads of my fastq files so that I can decide the cutoff for…

STICR lentiviral library preparation and validation We synthesized a high-complexity lentivirus barcode library that encodes approximately 60–70 million distinct oligonucleotide RNA sequences (STICR barcodes). STICR barcodes comprised three distinct oligonucleotide fragments cloned sequentially into a multicloning site within the 3′ UTR of an enhanced green fluorescent protein (eGFP) transgene under…

Significance Putatively ancient asexual species pose a challenge to theory because they appear to escape the predicted negative long-term consequences of asexuality. Although long-term asexuality is difficult to demonstrate, specific signatures of haplotype divergence, called the “Meselson effect,” are regarded as strong support for long-term asexuality. Here, we provide evidence…
