Is metaviral mode's Length threshold flexible?

Thanks for all the work devs.

I'm comparing metaviral SPAdes with standard SPAdes+virsorter2. Usually we end up placing a 10Kbp threshold on sequence length post-hoc, but I'm wondering how increasing the Length threshold (as mentioned in the paper) to a higher value would affect the graph assembly? From the paper:

We classify such a path as long if its length exceeds a threshold Length (the default value 1000 nucleotides) and high coverage if its coverage exceeds a threshold Coverage (the default value 5×). Long high-coverage paths represent putative sequences of linear viruses.

I've found similar looking thresholds in the hybrid_aligner defn in config.info, but that might be for hybrid assembly specifically:

spades/src/projects/spades/configs/config.info

Line 212 in 5fd841c

long_read_threshold 1000

Describe the solution you'd like

• should the length parameter be considered flexible? Can it be referenced from the CLI?
• Would modifying the value above change the programme as intended, or are those parameters for long/short hybrid assembly? If not, is there another location this can be increased from 1,000 to (e.g.) 10,000?

Describe alternatives you've considered

Currently, holding off on brutalising the lovely code.

Thanks for the help.
