In this example, we have two arrays,array1andarray2. We use thenumpy.concatenate()function to join these two arrays end-to-end, resulting in a new array that includes all elements from both input arrays in their

Using JTax, we assessed the benefit of joining paired reads for classifica- tion and compared the annotation accuracies by several top classifiers: RDP classifier, SINTAX, and two methods based on local and global alignment respectively. In addition, we analyzed our real Illumina PE data using...
