However, this single read contains sequencing errors and the region would be impossible to assemble for the de novo assembler. To use the Reassemble Regions tool start out by marking a region around the area to reassemble, right click and assign an annotation to the selected region by clicking Add annotation. The annotation will be used to define the region to reassemble if using the wizard driven version of the Reassemble Region tool. Alternatively it is possible to click on the selected sequence and select Reassemble. In both cases the reassemble tool will autonomously expand the region used for reassembly, which further will be highlighted with an annotation.
Toolbox | Genome Finishing Module () | Reassemble Regions ()
This opens the dialog shown in figure 10.2.
Next, select annotations for the regions to reassemble by clicking on the () (figure 10.3). Click Finish.
If the Reassemble Region tool has been capable of solving the problem, the sequence will now be reassembled as shown in figure 10.4. If the Reassemble Region tool was incapable of correcting the problem the black pop-up box will announce this and the sequence will remain unchanged.
