Passing parameters to a protocol?

[morefigs]

I wish to pass a parameter to a protocol after it has been uploaded to the robot. This would allow things like changing how many wells are dispensed into without having numerous similar protocols.

What is the recommended way (if any) to pass parameters that can be read by a protocol file?

I can't see an obvious way of passing parameters to the protocol file when uploading a protocol (POST /protocols) or creating a run for a protocol (POST /runs) via the HTTP API.

Ultimately I want the protocol to be able to accept parameters like this:

from opentrons import protocol_api

def run(protocol: protocol_api.ProtocolContext, num_wells: int):
    # use `num_wells`...

I noticed that protocol has a bundled_data attribute, but that only seems to be useable when uploading a protocol via the CLI and not the HTTP API, correct?

For anyone with the same problem my workaround was to dynamically inject parameter values into the Python protocol file before uploading: https://github.com/morefigs/opentrons-http-api/blob/main/examples/robot_client/upload_parameterized_protocol.py.

Hey, I'm running into similar issues where I want to run multiple protocols dynamically after each other but want to use parameters to keep track of used tips, however the page you're referring too seems to be lost. Do you still have the working method or something similar that works?

@MetsvR I ended up developing a private solution to this, feel free to email me at my username at gmail if you'd like to chat offline about it.
