--macs2-string parameter: can I use --control?

[vidaletal]

Thank you again for this tool,

I'm trying to use the MACS2 parameter --control using Hi-C as input. However, I'm unsure how to proceed with the command to have the same effect as it has on regular ChIP-seq.

Can you please help me? What would be the input in this case? Would be the .validpairs of the Input?

Thank you for your time.
