There are two options to filter reads: Subsample reads and Filter by read length. 

To Subsample reads, specify how many reads you want to keep for every nth reads. For example: if the user specifies to "Keep one read for every 10 reads" (Figure 1), this means that for every 10 reads, the program will keep only 1 read. This is equivalent to keeping 10% of the data.

To Filter by read length, set the read length limits by choosing the minimum and maximum read length(s) to keep.
