Clustering results and performance of Gclust at 90% eMEMi using 16 threads

Dataset	No. of sequences	No. of clusters	Running time (min)
Viral data	9578	9101	8.7
Archaeal data	38,381	16,064	88.0
Fungal data	79,365	68,698	1322.8
Bacterial data	112,111	105,867	7678.8

Note: The parameters used for clustering are as follows: -minlen 41 -both -nuc -threads 16 -chunk 400 -loadall -memiden 90 -rebuild -ext 1 -sparse 4. Parameter “-both” indicates that Gclust compares both strands of DNA sequences. MEM, maximal exact match. eMEMi, extended MEM identity.
