236 Made Q-peaks in a database entry valid. The Q-peak behaves like a carbon atom as in SHELX.
235 Updated email addresses.
234 Improved fragment search.
233 Fixed some accidental HFIX instructions.
232 Fixed rmsd value of fragment fit.
231 Removed numpy dependency for fragment fit.
230 Added "REM HFIX ..." to the list of restraints for fragments in residues.
229 Fixed wrong atom name in some restraints.
228 Fixed crash when solely "resi" occurs in the res file.
227 Fixed bug in restraints generation.
226 New fragments PMe3 and tBu, thanks to Krzysztof Radacki.
225 Fixed bug where fragments got wrong orientation.
224 Fixed bug where certain fragments got really large with DFIX command.
223 Fixed acetone restraints. Added test for inconsistent restraints with two atom pairs.
222-1 Fixed damaged numpy in Windows installer.
222 Fixed faulty 1,3 restraints in benzene.
221 Separated restraints and fragment during transfer. The restraints are now always inserted after
UNIT. The new fragment is always located before HKLF. This has the advantage that it does not depend on
the position of the DSR command and the SAME instruction has always the better fragments
as reference. Also, the often demanded sorting of the residue numbers should be in an increasing order now.
I also discarded the fragment fit with SHELXL FRAG/FEND. This implies that DSR now relies
on the numpy package. If you have just auto-updated DSR for a long time,
you might have to reinstall DSR from the installer one time in order to get it running.
Non-Windows users have to make sure that numpy is installed in addition! The Windows installer
includes the numpy package and should run just fine.
220 Allowing space characters in fragment search. Fixed bug where cf3 group generation could fail.
219 Adding "SIMU 0.04 0.08 1" to all restraints. This is necessary, because "SIMU_XYZ atoms"
only affects each residue in itself and not to atoms of residues near each other.
218 Fixed Exception occurring when source atoms had lower-case names.
217 Fixed linux packages.
216 New fit procedure should be stable now. In windows, you need to install the installer
executable once! DSR needs numpy for the faster fit now. Without numpy, the old
fragment fit is used.
215 Kabsch fit resulted in wrong translation of the fragment in some cases. This is fixed now.
214 Fixed external restraints with Kabsch fit. All feature should work now.
213 Added fragment fit with Kabsch algorithm instead of FRAG/FEND fit. This runs much faster
for large structures. This version might be unstable and not all features are supported,
but regular fragment fit with or without RESIdues and PARTs work.
212 Fixed SFAC with exponential parameters. Teflat fragment added. Added Trifluorbenzene.
211 More fragments: Dimethyl ammonium, tert-Butyl isocyanide, improved replace mode.
210 Added check for DFIX/DANG if the d value is larger than the sigma (as it should be).
DSR now ignores fragments that do not contain atoms. Less output during fragment fit
(wR2 and Gof were useless). Fixed line endings in start script. This should fix
updates on Unix systems.
209 Added 4,4'-Di-tert-butyl-2,2'-bipyridine and TEMPO fragments, users manual updated esp.
residues chapter, optimized restraints, fixed Acetonitrile restraints (why did nobody
208 Changed self-update process to be secured by checksums and ssl.
207 When using residues, DSR will now introduce a SAME_name 'first atom' > 'last atom'
to the list of restraints. First/last atom means first and last atom from the
respective fragment. This will make distances in all residues more consistent but should
do no harm.
Restructured dbfile.py a lot. Acess to the text database is now clearer and the parser
easyer to read.
206 Added Thiophen and 1,2,3,4-Tetrafluorobenzene.
205 Added SO2. Added full SHELXL-2017/1 compatibility (Except for chain IDs). Fixed
restraints in acetonitrile.
204 Added Methyl tert-butyl ether to the DB. Small fix for CF3 groups. Refractured some code.
203 Added logfile 'dsr-log.lst' to dsr output. Every last dsr run is now in the
'dsr-log.lst' file. Improved detection of already used restraints. The standard
deviations are now ignored for detection of duplicate restraints. This prevents
adding new restraints, although they are alredy there but with different values.
Added two more ether conformers (zigzag and only one side angled).
202 Greatly improved search results of "dsr -s name". A bug prevented to display
very similar names in the search results.
201 Fixed bug in threefold disordered CF3 group. Fixed -target option. Q-peaks
with -target can now have duplicate names. Removed FLAT in alkanes.
200-1 Added missing python27.dll in Windows package. Fixes "unknown error" in
ShelXle GUI (Thanks to Christoph Wölper).
200 Startup speed improvements. Added possibility to define target position
of atoms as coordinates (-target option“).
199 Added documentation how to control DSR with an external user interface.
Hexamethyl benzene fragment added. DSR inserts a comment about the origin
of the fragment into the res file.
198 Fixed some error messages. Added Leucine and Lysine. Improved search behavior.
Improved sorting of fragment list. Added [SbF6]-. SFAC names are now case-insensitive.
197-1 2,6-Dichlorobenzene added.
197 Fixed bug that prevents using more than nine free variables. Added
Dichloroethane and TMEDA fragments, RSS-Feed, unit tests, more search results.
196 Improved C20, C60 and C70 fragments. Now they all have restraints and
optimized geometry. Fixed case sensitivity bug. Improved FLAT restraints.
Added CF3, CF6 and CF9 fragments as dummy to the database. Improved unit tests.
195 Slight speed improvement. Cleaner code (needs more cleaning). Fixed too
optimistic replace mode in 194. External restraints shouuld work again.
193 Added auto updater to DSR. Run "dsr -u" to update to the most recent version.
192 Fixed strange characters in fragment list in Linux and other Small fixes.
191 Prevent NEGATIVE OCCUPANCY FOR ATOM XX warning in case of wrong
free variable values before fit. Added Isopropanole. Optimized examples.
Updated user manual. Fixed minor problem in case no shelxl executable is
found during fit in ShelXle.
188 Fixed bug that produces "dsr: error: unrecognized arguments: [...]" if
SHELXL was located in a directory containing space characters.
Fixed bug where "FVAR 1" ended up as 1000000.
Added all natural amino acids. Improved FLAT restraints.
187 No CF3 groups inside of residues allowed anymore. Fixed exception when
DSR tries to delete a file.
MACOS: Fixed broken startup script.
186 Fixed bug in sorting of names list. Made outlier test for SADI a bit weaker.
Added Fluorobenzene. User manual update.
185 Added COD to database. Fixed bug where 'cf3fit' could delete the first atom
in the res file (Thanks to C. Maichle-Moessmer for reporting). Fixed
damaging of L.S. command with more than one parameter.
184 PMDETA and DMAP fragments added, Fixed bug where cf3fit could not handle
isotropic atoms (Thanks to C. Maichle-Moessmer for reporting).
183 New fragments, improved handling of relative paths for external restraints,
restore refinement cycles after DSR run.
182 IMPORTANT! The default path for the user database is now the users home
directory! For example /home/username/dsr_user_db.txt in Linux and
C:/users/Username in Windows Vista and later. The DSR_DB_DIr environment
variable is now deprecated.
This version of DSR is not compatible with the DSR GUI in ShelXle-1.0.758
ShelXle 758 expects the user database file in the DSR directory while later
versions will expect it in the users home directory.
The fragment names in the listing output are now mostly sorted correctly.
An unreadable SHELXL executable will not create an exeption anymore.
181 Fixed bug where external restraints produced "illegal instruction" error
in SHELXL. AFIX 9 and +dfixfile is now recognized by a unique id.
External restraints with a rigid group produced an invalid RESI None None
180 Moving version format to integer. Final export format for the ShelXle GUI.

Success and fail reports about the restraint generation would be highly
Separate files with restraints e.g. in a +FILENAME.dfx file are now implemented
(system command line option -re). Full fragment names are now listed with
"dsr -l". The output of -l
now automatically fits to the command line width.
More meaningful comments about the import from a GRADE fragment are now
included during the import
and export. Multiple lines of REM in the database are now supported.
The molecules of the paper about "X-ray analysis on the nano-gram to micrograms
scale using porous complexes"
from Inokuma, Y. et al. Nature 495, 461�466 (2013) are included!
