Serial cloner two sequences3/27/2023 You will see a view like the one shown below. From the Open View dialog choose Multi-pane Cross Alignment View. To view this alignment right click on it in the Project View and choose Open New View in the context menu. Step 4: Viewing the Alignment in Multi-pane Cross Alignment View As the alignment is performed locally, repeat filtering is only available to external users if the repeats for the components have also been loaded locally. Note: The Find Overlaps tool first looks for a BLAST alignment between the component sequences, and if none is found, goes on to perform a banded global alignment. When the alignment is complete, the result will appear in the AC040978.8_AC115836.5_alignment project in the Tool Result folder. Use the default alignment parameters for this alignment. In the dialog that opens, select AC040978.8 as Sequence 1 and AC115836.5 as Sequence 2. In the Run Tool dialog, choose Find Overlap between DNA Sequences and click Next. Then select Tools=> Run Tool from the main menu. Select both sequences within the project tree. This alignment expresses the relationship seen between two clones assembled sequentially in a tiled BAC assembly. We will generate a specialized alignment for these two sequences - an overlap alignment. You can rename projects by selecting the project (green folder named 'New Project' in the project tree), right-clicking, and selecting Properties. The other way is just to select the sequences and move them using drag and drop functionality. This can be done by selecting the sequences, right clicking and choosing Cut, then selecting the Sequences folder, right clicking, and choosing Paste. Now let us put our sequences in the Sequences folder. In the New Project Folder dialog that appears, names the folder Sequences. Right click (or control click on the Mac OS) on the 'Data' label and choose 'New Folder' from the contextual menu. Let us create a folder called Sequences in our project and add both sequences to this folder. Now there is a 'New Project' in the Project Tree View. Note: the other way to add data to the project is to use Search View (see Basic Operation tutorial, Step 3). Click File => Open, in dialog select Data from GenBank and paste AC040978.8, AC115836.5 into the Accession to Load box, click Next and Finish. Step 2: Selecting Sequences to Alignįor this exercise we selected two clone sequences (AC040978.8, AC115836.5) that are parts of the tiling path track for Human chromosome 8 (NC_000008) and are known to have overlap.įirst let us add both sequences into a new Genome Workbench project. We will use Genome Workbench to review alignments and how to visually inspect annotations on two sequences in an alignment. This tutorial assumes the user has already reviewed at least Basic Operation tutorial and has a basic knowledge of the program. It uses the Find Overlaps tool, which is designed to look for dove-tail (end-to-end) alignments. This tutorial will take you through the steps involved in looking for an alignment between two DNA sequences. Generating and Viewing Sequence Overlap Alignment Step 1: Introduction
