Sars-Cov-2 and Mers sequences from human host with no unknown characters (Q6694266)

The datasets are organized as follows: first column, number of bases in a given sequence; second, third, fourth and fifth columns, number of bases of type A, C, G and T, respectively, in the same sequence.  1) Sars-Cov-2 dataset. This dataset contains number of bases for the complete genome sequences from a human host, with none unknown characters.  In the NCBI database, there are about 950.000 sequences with these characteristics. 2) Restricted Sars-Cov-2 dataset: This dataset contains number of bases for the complete sequences from a human host, with no unknown characters, with 29903 bases, that is of the same length as the reference sequence NC045512.2. We obtained, from the NCBI database, about 5600 sequences with such features. 3) Mers dataset: This dataset contains number of bases for the complete sequences of about 200 complete genome sequences from a human host, with no unknown characters.
