Why does BioAssay HTS fail when I import a ChemFinder Database into plates using the default physical plate type 384-well plate?

If your ChemFinder file contains plate coordinates using an alphanumeric designator such as "A-1", you will see above behavior. The default 384 well physical plate type uses numbers to denote both rows and columns.  A new physical plate type must be defined to allow letters to denote rows and numbers to denote columns.

To do this:

1. Go to Settings > Plate Setup > Physical Plate Types. 
2. Click Edit.
3. Click Add to create a new physical plate type.
   A new row appears.
4. In the new row, enter (from left to right):
   • Name: 384 Well Plate (Lettered)
   • Well Capacity: <Capacity of your choice>
   • Units: <units of your choice>
   • Supplier: <Supplier of your choice>
   • Pre-barcoded?: <Pre-barcoded of your choice>
   • Row Count: 16
   • Column Count: 24
   • Row Prefix: <blank>
   • Column Prefix: <blank>
   • Letter Rows?: Yes
   • Letter Columns?: No
   • Number First: Row 
5. Go to Settings > Plate Setup > Plate Formats and add a new plate format called 384 Well Plate Format using the "384 Well Plate (Lettered)" physical plate type.  (You may have to close and reopen the Plate Formats view using the X at top right to see the new plate format).
