pylabrobot.liquid_handling.backends.hamilton.base.HamiltonLiquidHandler.get_channel_spacings

HamiltonLiquidHandler.get_channel_spacings(use_channels: List[int]) → List[float]

Get the per-channel occupancy diameter for each channel being used.

Each value is the channel’s occupancy diameter - the physical space it takes up. The required center-to-center distance between two adjacent channels is the sum of their radii: spacing[i]/2 + spacing[j]/2.

Parameters:

use_channels (List[int]) – The channels being used, in order.

Returns:

List of per-channel occupancy diameters (mm), length = len(use_channels). Defaults to GENERIC_LH_MIN_SPACING_BETWEEN_CHANNELS (9mm) for all channels. Backends with variable channel spacing should override this.

Return type:

List[float]

Note: This assumes channels spread along Y. Backends where channels are fixed in Y (e.g. OT2 with 2 channels at fixed X spacing) should either override this or signal that Y-spread is not supported via a supports_y_spread property.
