Hi Chris,
Yes, I have seen quite a few inconsistencies in screen formulations.
Errors in listed conditions include recipe changes, but also typos both
in the vendor description and in the database entries. At the moment I'm
building a list of all discrepancies of the screens in the Formulatrix
database together with the date found. This is a tedious work in
progress but I'm happy to share the list sofar with people interested
(offline). It will be published on the web site when complete. In the
meantime, it is wise to double-check each hit condition found on the
vendor web site, and in the cases where the exact composition is not
published ask the vendor directly.

HI,
I've recently seen two examples where the description of a screen in a local
database was different to the current one on the manufacturer's web site. This
happened in two different labs, using different software, and with different
screen manufacturers.
This could potentially lead to an optimisation screen that finds no hits,
because the wrong condition is being optimised. Does anyone have experience of
this? Am I just looking at a few one-off errors, or is there a general problem
here?
The ideal solution is for screen manufacturers to give version numbers to their
screens. Failing that, a good fix at the laboratory is to download the screen
description every time a deep-well plate is received, and second best would be
to download it every time a trial plate is set up. If there is a real concern
here, we will implement one of these in xtalPiMS.
Regards,
Chris
