What is Sample Reads?
The Sample Reads tool allows a user defined reduction of the number of reads. This can be relevant when editing contigs with a high coverage as an excessive amount of reads can be overly resource demanding and cause the edit options in the read mapping editor to disallow performing actions. The Sample Reads tool is very useful for reducing the size of data sets. The sampled reads can sequentially be mapped to contigs in the Contig Aligner. In this way the speed of many edit operations in the contig aligner can be increased significantly without any loss of important information. The preservation of a high coverage is only necessary for de novo assembly. After de novo assembly a large number of reads does not add extra to the analysis.
