What's the meaning of the -H option of LA4Falcon?

[nottwy]

I check the sequences in the output of LA4Falcon and find that there are some sequences whose length is less than the CUTOFF I set.
So What's the meaning of the -H option of LA4Falcon?

I have read the following words in your website, but it's not clear enough.
‘’Output data from a Dazzler DB into fasta format for FALCON. You can supply the argument -H with an integer value to filter reads below a given threshold.‘’
But how to filter?
