Dioscuri

Dioscuri is a Python package for working with Gemini WorkList (gwl) files and objects.

A Gemini worklist file is a text file that contains pipetting instructions for the Tecan Freedom EVO robots. Dioscuri uses the Freedom EVOware (v2.7 or equivalent v2.8) software's specification of the gwl format. It also supports the timer record for the Fluent robot.

Dioscuri is a name for Castor and Pollux, the twins who were transformed into the Gemini constellation in Greek mythology.

Install

pip install dioscuri

Usage

import dioscuri

aspirate = dioscuri.Pipette(operation="Aspirate",
                            rack_label="Source1",
                            rack_type="4ti-0960/B on raised carrier",
                            position="3",
                            volume="50")
aspirate.to_string()

dispense = dioscuri.Pipette(operation="D",
                            rack_label="Destination",
                            rack_type="4ti-0960/B on CPAC",
                            position="1", 
                            volume="50")

wash = dioscuri.WashTipOrReplaceDITI()

worklist = dioscuri.GeminiWorkList(name="my_worklist",
                                   records=[aspirate, dispense, wash])
worklist.records_to_string()

print(worklist.records_to_string())
# A;Source1;;4ti-0960/B on raised carrier;3;;50;;;;
# D;Destination;;4ti-0960/B on CPAC;1;;50;;;;
# W;

The worklist can be saved in a text file:

worklist.records_to_file("picklist.gwl")

A gwl file can also be read into a worklist:

worklist = dioscuri.read_gwl("picklist.gwl")
