This is a collection of things users feel XDS should handle differently from how the program currently does.

On this page (only), it would seem useful if a user who edits this puts his "signature with timestamp" (second button from the right in the menu bar above) after the sentence s/he inserts.

Important

• none so far

Would be nice to have

• A breakdown of R_meas by frame number, as currently only available from XDSSTAT. This would be useful in order to identify bad frames. --Kay 14:00, 12 November 2007 (CET)

• Templates of XDS.INP currently have

!EXCLUDE_RESOLUTION_RANGE= 3.93 3.87 !ice-ring at 3.897 Angstrom
!EXCLUDE_RESOLUTION_RANGE= 3.70 3.64 !ice-ring at 3.669 Angstrom
!EXCLUDE_RESOLUTION_RANGE= 3.47 3.41 !ice-ring at 3.441 Angstrom
!EXCLUDE_RESOLUTION_RANGE= 2.70 2.64 !ice-ring at 2.671 Angstrom
!EXCLUDE_RESOLUTION_RANGE= 2.28 2.22 !ice-ring at 2.249 Angstrom

This list may/could be completed by

!EXCLUDE_RESOLUTION_RANGE= 2.102 2.042 !ice-ring at 2.072 Angstrom - should be strong
!EXCLUDE_RESOLUTION_RANGE= 1.978 1.918 !ice-ring at 1.948 Angstrom - may be weak
!EXCLUDE_RESOLUTION_RANGE= 1.948 1.888 !ice-ring at 1.918 Angstrom - should be strong
!EXCLUDE_RESOLUTION_RANGE= 1.913 1.853 !ice-ring at 1.883 Angstrom - may be weak
!EXCLUDE_RESOLUTION_RANGE= 1.751 1.691 !ice-ring at 1.721 Angstrom - may be weak

Please note that I did not optimize the widths (in particular the last one should probably be something like 1.741 1.701 or 1.731 1.711), and that the ranges of the 2nd, 3rd and 4th ring overlap (and thus could be combined and narrowed to something like 1.958 1.873). --Kay 14:30, 12 November 2007 (CET)

• INCLUDE_RESOLUTION_RANGE= should be respected by IDXREF because this could be used to prevent ice rings from disturbing the indexing. Drawback: one would have to change INCLUDE_RESOLUTION_RANGE= after running IDXREF.
  Probably better: EXCLUDE_RESOLUTION_RANGE= should be respected by IDXREF. Drawback: geometrical parameters (in particular the direct beam position) are unrefined when resolution is calculated in IDXREF.
  Probably best: a new keyword for this purpose.
  For a workaround, see Ice_rings.

• a keyword REJECT_ALIENS= with a default of 20. This would be the cutoff for automatic rejection of "aliens". --Kay 10:29, 27 November 2007 (CET)

• an error message and program stop if the files given as parameters of X-GEO_CORR and Y-GEO_CORR cannot be found. Currently the program continues silently, which might lead to suboptimally processed data.--Kay 22:19, 12 December 2007 (CET)

• Automated Direct Beam Position Recognition from Direct Beam Shots: The undocumented DIRB option should be announced and extended. I would suggest the following: a new input keyword "NAME_OF_DIRB_FRAME=" instead of interactive input is used to specifiy the direct beam shot frame. As a default "NAME_OF_DIRB_FRAME=" should use frame 0 of the current Name_Template_of_data_frames selection. Avoiding interactive input would facilitate automated script based processing and avoid the use of erroneous direct beam position form headers or manual input.--Tmaier 13:24, 13 December 2007 (CET)

Cosmetical

• CORRECT should print out MAXIMUM_NUMBER_OF_PROCESSORS= , and the actual number of processors used. --Kay 13:55, 12 November 2007 (CET)

• CORRECT should print out MINIMUM_I/SIGMA= . --Kay 14:24, 13 November 2007 (CET)

• BACKGROUND_RANGE= should have a better default (e.g., the first five frames of the DATA_RANGE). The default currently appears to be 0 0. --Kay 14:45, 12 November 2007 (CET)

• document X-GEO_CORR and Y-GEO_CORR.--Kay 22:18, 12 December 2007 (CET)
