Echo Worklist

A closer look at the Echo worklist format.

As we saw previously a worklist is essentially a CSV or a text file with information (commands consisting of individual lines or records with data and instructions) for the liquid handler machines. Exporting an Echo worklist from  BUILD results in a .csv file following this format:

  • Source Plate Name, Source Well, Destination Plate Name, Destination Well, Transfer Volume.

  • Transfer volumes are in nL.

  • Wells are identified through alphanumeric coordinates.

If you use Microsoft Excel to create or edit a CSV file for import, ensure that the standard separator for lists is a comma, and the decimal symbol is a period (i.  e. in Windows, under Control Panel > Clock, Language, and Region > Change date, time, or number formats > Formats > Additional Settings > List separator & Decimal symbol). Save your edited table in CSV format before closing Excel.
