print out a warning in such cases. If you find many warnings
being issued, contact the LOOS developers.
* Changed the rmsds tool to use a much faster algorithm (up to an
order of magnitude faster). There is no option to disable caching
now--if the cached subsets do not fit in memory, you will want to
subsample the trajectories.

2014-11-20 <[email protected]>
* Deprecated gridify() in dcd_utils.cpp
2014-10-21 <[email protected]>

output trajectory format and return a pTrajectoryWriter (boost
shared pointer to a TrajectoryWriter object).

(e.g. pPDB PDB::create(const string &fname)).
* Changed how all of the createXXXX() factory functions work...
They use a table binding filename extension to the appropriate
object create() function.
* Added Trajectory::description() to return a string describing
the trajectory format.
* Changed trajinfo to report the trajectory file's format
* Changed subsetter and mergetraj to use TrajectoryWriter.

upon successive frames in the trajectory.
* Fixed bug in rmsds tool where the average RMSD reported

* Changed Matrix operator[] to only check for out of bounds index
when debugging (i.e. -DDEBUG)
2013-10-15 <[email protected]>

2013-10-11 <[email protected]>
* Added Math::eigenDecomp() that calculates the eigenpairs for
the passed DoubleMatrix (using DSYEV).
* Added gnm-traj and anmo-traj tools for analyzing trajectories
using elastic network models.
2013-10-08 <[email protected]>
* Changed how atomid's are handled in LOOS. Previously in LOOS,
atomid's had special meaning. Not only should they be unique, but
they also identify which "slot" in a trajectory frame that a
specific atom was located. This meant that if a model's atomid's
didn't begin at 1 were not contiguous, then bad things could
happen. Now, LOOS assigns and atom "index" to every atom as it is
being read in by the appropriate model format class (e.g. PDB,
Amber, etc). This index tells LOOS which slot to use with a
trajectory, rather than the atomid. In general, this should just
work. For more information, see the Doxygen documentation for
Trajectory or the LOOS FAQ.
* Changed all Trajectory-derived updateGroupCoords() to honor the
atom index information. This affects primarily the PDB-based
trajectory classes which used to ignore atom metadata if the
passed AtomicGroup was the same size as the trajectory frame.
* Changed updateGroupCoords() to use NVI idiom. Now calls
updateGroupCoordsImpl() in the derived classes.
2013-10-01 <[email protected]>
* Added smooth-traj tool for smoothing trajectories
2013-09-13 Tod Romo <[email protected]>
* Released 2.0.6
2013-08-26 <[email protected]>

2013-08-22 <[email protected]>
* Added new flag to rdf to allow the two selections to be split using
different methods.
2013-08-20 <[email protected]>
* Fixed bug with XTC trajectories when the system contains too
few atoms (<= 9). Gromacs does not compress the coordinates, but
LOOS expected all system sizes to have compression.
* Changed transition_contacts to add a --smoothed-transition
option to use a tanh() function to effectively smooth the contacts
matrix when a contact is near the cutoff. This is now the default
behavior. (Nick)
2013-08-15 <[email protected]>
* Changed installation to now include python scripts if pyloos is
being built.
* Added .nc and .crd as Amber trajectory extensions. Note that
.crd for a structure is still interpreted as a CHARMM coordinate
file.
2013-08-12 <[email protected]>
* Fixed bug in serialize-selection where the output molecules were
interleaved rather than each chunk of T-frames consisting of a
single molecule (e.g. it would have been mol 1, mol 2, mol 1, mol
2 instead of mol 1, mol 1, mol 2, mol 2)
* Added --fullhelp output to phase-pdb
* Fixed bug in phase-pdb where a duplicate (and incorrect) set of
bonds could be added when using --chunk and --rows options
2013-08-01 <[email protected]>
* Added a new tool to Packages/PyLOOS: protein_tilt.py computes the time
series of the tilt angle for a transmembrane protein by averaging the
tilt vectors of individual selects (e.g. individual helices)
2013-07-26 <[email protected]>
* Fixed hierarchy so that it now catches bad input and generates a
useful error message rather than segfaulting...
* Fixed multiple tools to more gracefully handle problems when
opening files.
2013-07-23 <[email protected]>
* Changed coverlap tool to internally use double-precision for
eigenpair matrices. This resolves a fringe-case where coverlap
would fail with a conversion error when using eigenpairs from the
ENM suite.
2013-07-23 Tod Romo <[email protected]>
* Fixed gmxdump2pdb.pl so that it can handle cases where there are
more topology segments than molecular segments (as can happen with
bilayer systems)
2013-07-19 <[email protected]>
* Added link to tutorial on LOOS in documentation
2013-07-03 <[email protected]>
* Added change to cross-dist. Disambiguate sign of PCA vectors

2013-07-01 <[email protected]>
* Fixed gmxdump2pdb.pl to NOT use hybrid-36 encoding for the
PSF file.
2013-06-25 <[email protected]>
* Fixed potential bug in DCD reader nstep was used internally in
place of nfile.
* Fixed bug when instantiating DCD files with nfile==0 so it
doesn't immediately throw an error.
* Added fixdcd tool to update a DCD header (in-place) with the
correct # of frames.
2013-06-19 <[email protected]>
* Released 2.0.5
2013-06-18 <[email protected]>
* Changed rmsd2ref so that it no longer caches trajectory frames
2013-05-29 <[email protected]>
* Added --xyonly option to aligner so that alignment (rotations)
only occur in the x,y plane. Note that all systems are translated
so their centroids are coincident, so there may be a
Z-translation.
* Changed AtomicGroup::superposition() to not throw if the
alignment matrix is singular. Instead, aligner will warn if too few
atoms are selected instead.
* Changed setup scripts to prepend paths rather than append
* Added transition_contacts tool from N. Leioatts
2013-05-22 Tod Romo <[email protected]>
* Changed renum-pdb so that connectivity is preserved
2013-05-17 Tod Romo <tromo@gorgoneion>
* Changed timeAsString() to accept an optional precision parameter
for the seconds field.
2013-05-07 <[email protected]>
* Updated native_contacts tool. Fixed an off-by-one bug that
caused the last residue in the selection to be handled wrong. Switched
to using the standard program options, so now the selection defaults to
name == "CA", and is prefixed by --sel. Added new option to output the
timeseries of individual contacts to a separate file. Added new option to
exclude the backbone atoms.
2013-05-01 <[email protected]>
* Added serialize-selection tool. Given a trajectory with T
