ragtag_scaffold.py: error: unrecognized arguments

[athenasyarifa]

Hi,

Not sure if this is entirely my fault for not understanding the Wiki page, but I have not been able to successfully run ragtag_scaffold.py with other optional parameters. It would run normally if I didn't use any optional parameters, and I am running RagTag v.2.1.0

For example, the following commands would run successfully:
ragtag.py scaffold reference.fasta scaffolds.fasta
ragtag.py scaffold -o ./output reference.fasta scaffolds.fasta

But the following would invoke "ragtag_scaffold.py: error: unrecognized arguments <reference.fasta> <query.fasta>"
ragtag.py scaffold -i 0.5 -a 0.9 -s 1.0 -r 1000 -f 10000 -o ./output reference.fasta scaffolds.fasta

Can somebody point out what I did wrong?
Thank you in advance!

Best,
Rifa
