r27698 | bugman | 2015-02-20 14:56:11 +0100 (Fri, 20 Feb 2015) | 5 lines
Added one more check to the Structure.test_bug_23295_ss_metadata_merge system
test.
The test would pass if no HELIX or SHEET records were to be written to the
PDB file.
........
r27699 | bugman | 2015-02-20 15:41:11 +0100 (Fri, 20 Feb 2015) | 3 lines
Fix for the Structure.test_bug_23295_ss_metadata_merge system test and
additional printouts.
........
r27700 | bugman | 2015-02-20 15:49:23 +0100 (Fri, 20 Feb 2015) | 9 lines
Bug fix for the SHEET PDB records created by the structure.write_pdb user
function.
The current and previous atom parts of the record were not being correctly
formatted. This was
simply using the %4s formatting string. However the PDB atom format is
rather more complicated. To
handle this, the new _handle_atom_name() helper function has been added to the
lib.structure.pdb_write module. This is now used in the atom() and sheet()
functions for
consistently formatting the atom name field.

r27701 | bugman | 2015-02-20 15:50:52 +0100 (Fri, 20 Feb 2015) | 6 lines
Fix for the Structure.test_pdb_combined_secondary_structure system test.
The SHEET PDB record check was incorrect and was checking for the improperly
formatted atom name
field, which has now been fixed in relax.
