UCSC genome browser vs IGV • Some tracks are unique to one of them • IGV navigates faster because it runs locally • IGV allows you to create a new genome • It’s easier to jump to view the same region in another species with the UCSC browser 4 The aforementioned HEK293 libraries were analyzed for splicing variation by generating Sashimi plots (IGV, version 2 Since the plot feature is incorporated in IGV, I am interested visualizing RNA-Seq data in IGV The Pg47 differentially expressed and positively regulated (log 2 1 8 1 were analyzed for splicing variation by generating Sashimi plots (IGV,version 2 From my RNAseq data analysis, we have a few candidate genes that show alternative splicing in my samples (B) Analysis of AS events by RT-qPCR for selected genes in control- (MS) and flg22-treated (100 nM for 6 h) Col-0 and smd3b-1 plants Sashimi plots were created from RNA-seq data using Integrative Genomics Viewer (IGV) Sashimi plots visualize splice junctions for multiple samples from their alignment data alongside genomic coordinates and a user-specified annotation track Repeat for blue (liver) track Navigate to the region of interest, right click the tracks window and select “Sashimi plot” from the menu The x-axis labels of Sashimi plot panels should be hidden, since the gene-exon plot will display the genomic coordinates org/igv/Sashimi The Sashimi plot and the gene-exon plot should share identical x-axis range and axis breaks 上述示意图表示的是一个外面子跳跃的可变剪切事件，最下方是可变剪切isofrom的示意图，分别对应inclusion isofrom 和 skipping isofrom; 采用RPKM值量化表示样本中对应的测序 News-in-brief / 02 Sashimi-Plotを描画してみる。 9 At least one split read and ≥2 discordant pairs were required to identify chimeric HPV-host transcripts, which were visualized using the Sashimi plot function of IGV (Katz et al The Sashimi plot and the gene-exon plot should share identical x-axis range and axis breaks * • Visualises*genomic*data(expression,* ChIP, resequencing,*mul(ple*alignment,*shRNA) For a more holistic view, IGV's Sashimi plot can be modified to exclude spurious junctions supported by few reads Sashimi plots Alternative Splicing V One of the most commonly seen internal contaminants is the presence of DNA in RNA-Seq samples Reads originating from the forward primer are shown in red; reads from the reverse primer are in blue (from the Ensembl database), along with splice junctions from the IGV browser Cheng Sashimi Plot Mutant 2: B6, D6 GFF file recording the informations of your alternative events While this trend is Run IGV with the Sashimi plot feature enabled: java -jar -Xmx2g -DenableSashimi="true" igv Gene schematics showing the AS events in green, as well as the Sashimi plots obtained by IGV showing the total read numbers for each junction IGV displays the Sashimi plot in a separate window and allows for more manipulations of the plots than the junctions track The coverage for each alignment track is plotted as a bar graph Download the IGV desktop applica This type of contamination is very easy to miss and won’t generally trigger any errors in a standard RNA-Seq analysis pipeline, but can cause significant bias in the quantitated data (I) Sashimi plot using IGV program shows the splicing changes of EED gene in BE2C and SK-N-AS cells after RBM39 knockdown, which indicates the missplicing among exons 7 to 10 sashimi plot 绘制 The Sashimi plot is displayed in a separate window groups (endothelial, epithelial and mesenchymal) for the region chr10:27040584-27048100 obtained by ggsashimi (A) and the sashimi-plot utility within IGV (B)
