RE: [sdpd] Fullprof: No reflections found---Check your input data

["Yokochi, Alexandre" <alex.yokochi...@orst.edu>]

Hi,

	OK, yet an additional commentary to htose by Armel and Guilhem, to
put things in perspective.  

	What this error message really means (as I deduced from personal
experience) is that the program could find no intensity for the phase you
think you have at the positions the reflections are being calculated.
Therefore check the cell parameters, etc, as advised by the others.

Dear All:

I got an error message while trying to refine by Fullprof says: No
reflections found---Check your input data. Could you please tell which part
of input data should i check?

Thank you very much!

  Dear Powder Diffraction Users,

  The Indexing step 1 of the SDPDRR-2 (Structure Determination by
  Powder Diffractometry Round Robin -2) is closed.

  Despite of more than 100 data downloads, only 6 contributions were
  received. This may indicate that the indexing bottleneck is still
  there. Answers for samples 4-8 are very scarce. Owing to some
  participant requests for giving more time to these 4-8 samples, we
  will accept post-deadline answers which will be marked as such.

  http://www.cristal.org/sdpdrr2/results/

  However, clear solutions have been provided for samples 1-3 which
  are now the subject of step 2 (structure solution and refinement) still
  running up to November 17th, 2002.

  Best wishes,

  Armel Le Bail and Lachlan Cranswick
