how does schema work?

[flomock]

right now I'm only able to use.
zoo schema "(a(b,c))" > firstSchema.json
if I would like to use the more specific schemata I always get an error, independent from entering just the name (influenza_a.json(b,c)) or entering the full path:
zoo schema "(/home/florian/.../schema/specific/influenza_a.json(b,c))" > InfluSchema.json

and how do I use the --fp? i tried it, didn't worked. --help wasn't much of a help
