What are bioinformatics cufflinks?
Cufflinks assembles individual transcripts from RNA-seq reads that have been aligned to the genome. Because a sample may contain reads from multiple splice variants for a given gene, Cufflinks must be able to infer the splicing structure of each gene.
What is Cufflinks RNA-seq?
Cufflinks consist of a suite of tools for differential gene expression analysis of RNA-seq data. It assembles aligned reads in a set of transcripts and estimates the relative abundances.
What is Cufflinks package?
Cufflinks assembles transcripts, estimates their abundances, and tests for differential expression and regulation in RNA-Seq samples. It accepts aligned RNA-Seq reads and assembles the alignments into a parsimonious set of transcripts.
What is Cuffdiff RNA-seq?
Cuffdiff finds significant changes in transcript expression, splicing, and promoter use. You can use it to find differentially expressed genes and transcripts, as well as genes that are being differentially regulated at the transcriptional and post-transcriptional level.
What is Cuffcompare?
Summary. Cuffcompare helps analyze the transcribed fragments (transfrags) in an assembly by: Comparing assembled transcripts to a reference annotation. Tracking Cufflinks transcripts across multiple experiments (e.g., across a time course)
What is FPKM?
FPKM stands for Fragments Per Kilobase of transcript per Million mapped reads. In RNA-Seq, the relative expression of a transcript is proportional to the number of cDNA fragments that originate from it.
What are bowtie TopHat and Cufflinks?
TopHat and Cufflinks are free, open-source software tools for gene discovery and comprehensive expression analysis of high-throughput mRNA sequencing (RNA-seq) data. It also covers several accessory tools and utilities that aid in managing data, including CummeRbund, a tool for visualizing RNA-seq analysis results.
What are GTF files?
The Gene transfer format (GTF) is a file format used to hold information about gene structure. It is a tab-delimited text format based on the general feature format (GFF), but contains some additional conventions specific to gene information.
How do you start a Cuffmerge?
From the command line, run cuffmerge as follows:
- cuffmerge [options]* ##Cuffmerge input files.
- -h/–help.
- -o
- -g/–ref-gtf.
- -p/–num-threads
- -s/–ref-sequence /
Is FPKM normalized?
The name “FPKM” – fragments per kilobase of exon per million reads – implies that FPKM is a measure of gene expression normalized by exonic length and library size, in contrast to raw counts.
What is a FPKM value?
What is TopHat algorithm?
TopHat is a fast splice junction mapper for RNA-Seq reads. It aligns RNA-Seq reads to mammalian-sized genomes using the ultra high-throughput short read aligner Bowtie, and then analyzes the mapping results to identify splice junctions between exons.
