+Outputs a gzipped fastq file where reads with more than the
+maximum number of allowed uncalled bases are not included.
+
+Threshold is the maximum percentage (ranging from 0 to 100)
+of uncalled bases that a read can have. Default value is 0,
+which means that a read with a single N would be discarded.
