Developer wishing to embed juicebox.js please see the project README, and post questions and issues to the github forum. To open an empty "browser" to dynamicallyĮxample: import juicebox_notebook juicebox_notebook. juicebox.js View On GitHub This page is obsolete. The configuration object is described in the The juicebox_notebook.Browser constructor takes a configuration object which is converted to JSON and passed to the juicebox.jsĬreateBrowser function. Colab notebooks display output in a sandboxed iFrameįor each cell, so these steps must be repeated for each cell in which juicebox-notebook is used. init ()įor a Jupyter notebook this should be done once per notebook. import juicebox_notebook juicebox_notebook. InstallationĪfter installing import and intialize igv_notebook as follows. ExamplesĮxample notebooks are available in the github repository in the "examples" directory of the github repository. Hi-C contact maps are valuable for genome assembly (Lieberman-Aiden, van Berkum et al. Use other annotations for more in-depth exploration of the results.Juicebox-notebook is an module for Jupyter and Colab notesbooks which exposes a python API thatĮnables creation and interaction with a juicebox.js instance in a cell. You can zoom in or scroll around in the heatmap to better understand where the DIRs occur in relation to each other and on the chromatin map. The blue boxes on the heatmap represent the significant DIRs. Here we can see a screenshot of Juicebox with the Rao 2017 data loaded and our annotations visualized on the heatmap. Go to Juicebox.js GitHub Page Read the Juicebox. The DIRs will appear as blue rectangles on the heatmap. Share Watch on Using Juicebox Assembly Tools to assemble the barrel medic Share Watch on The Hi-C contact maps available on individual genome assembly webpages were embedded using the Juicebox.js software from (Robinson et al., Cell Systems, 2017). Select chromosome 16 in both drop-down menus below the “Chromosomes” selection toolbar and click the refresh button. After loading it, the “rao2017Annotations.txt” annotations will be shown in the “Select 2D annotation file(s) to open” panel - select it and click the Open button to load in into Juicebox. tab/button, and navigate to the “rao2017Annotations.txt” file. Alternatively, use the View > Show Annotations Panel menu. Individual tools can be run as batch jobs or interactively. It should therefore be run on the login node. Juicer website The juicer pipeline submits jobs to the cluster and then exits. It was developed in the Aiden lab at Baylor College of Medicine/Rice University. This file has been pre-generated, right-click and save it from here.Īssuming the “Rao et al. | Cell 2017” “Auxin treated (6 hrs)” data is loaded, click the Show Annotation Panel button at the lower right corner of Juicebox window. Juicer is a system for analyzing loop-resolution Hi-C experiments. This function will create a text file in your working directory containing the annotations which can then be imported into Juicebox. exportJuicebox(rao2017, logfc_cutoff = 2, logcpm_cutoff = 1, p.adj_cutoff = 0.001, file_name = "rao2017Annotations.txt") Hi-C has identified new levels of chromosome organization such as A/B compartments, topologically associating domains (TADs) as well as large megadomains on the inactive X chromosome, while allowing the identification of chromatin loops at the genome scale. Here, we introduce Juicebox.js, a cloud-based web application for exploring the. Say your Hicexp object is named rao2017 simply run the following line of code in R. Contact mapping experiments such as Hi-C explore how genomes fold in 3D. Typically we assemble the genome with long reads and polish (long or illumina reads) prior to running the pipeline. You will want to select the main map for “Auxin treated (6 hrs)”.Īssuming you have already analyzed the data using multiHiCcompare and you now have a Hicexp object containing the comparison results you can use the exportJuicebox function to export the list of DIRs as an annotations file for input into Juicebox. Genome scaffolding with the Juicer, JuiceBox, 3D-DNA pipeline Here at the ISUGIF, we have used multiple different contig assemblers and had success with this pipeline. The Rao 2017 data are available in Juicebox by default under File > Open menu, “Rao et al. | Cell 2017”. We finally used Juicebox Assembly Tools v1.9.9 (Durand et al. We compared the data between the normal HCT-116 cells and the cells treated with auxin for 6 hours. BGISEQ-500 platform to sequence the Hi-C library, we obtained 87.60Gb of raw Hi-C data. For our example, we will use the data from Rao 2017.
