Seq (total number of sequences), Median (median length of sequences), Short (shortest sequence), Long (longest sequence), PQS (total number of predicted PQSs), Mean f (mean frequency of predicted PQS per 1,000 nt), Min f (lowest frequency of predicted PQS per 1,000 nt), Max f (highest frequency of predicted PQS per 1,000 nt), GC% (mean GC content). Note that 132 PQSs were in Nidovirales with Undefined host.
