Changes for IMOD 4.1.3

Changes marked with ** are particularly noteworthy, ones marked with * may also be of interest to typical users.

Changes in Tomogram Processing

** 2/21/10: Tilt modified to do multiple iterations of SIRT internally when possible (fixed X-axis tilt, no Z-factors or local alignments), using GPU if possible, and to do reprojections with local alignments on the GPU.

** 1/1/10: Tilt can now use use the GPU in a CUDA-capable NVIDIA card for all forms of backprojection and for reprojection from a reconstruction file not involving local alignments. It also allocates memory as needed for the particular reconstruction. To simplify the code, options for fast backprojection, replications, and negative slice increments were eliminated.

** 10/2/09: In Tiltxcorr, added the ability to track the centers of multiple patches specified as a regular array or by a model, and output a model that can be used for fiducial alignment; added anility to use boundary contours to constain the region correlated for alignment or the selection of patches tracked; added an option to iterate the correlation to increase the subpixel accuracy of the result; fixed the transform output when leaving the tilt axis at the center of a subarea; added an option to limit the range of shifts in the peak search.

** 8/10/09: Many changes to Ctfplotter: Eliminated two sources of inconsistency between Ctfplotter and Ctfphaseflip in the relation between defocus and frequency; implemented nearly exact shifting of spectra from off-center tiles instead of shifting by integer amounts; made the shifting variable so as to align both first and second zeros between off-center and central tiles; started caching power spectra for individual tiles so that after they are computed once it is quick to recompute a summed spectrum; added fitting to a CTF-like curve and to a polynomial and made the CTF-like fitting the default; reorganized the angle range dialog to put the important options at the top; revised the guide and added snapshots from various stages of working on an example set. Also added an option to both programs to invert the sign of the tilt angles, in case the set of angles gives reconstructions with inverted handedness.

* 3/14/10: Changes to Ctfplotter: it now shows a table of results that will be saved to file and that can be read in from a previous session. Tool buttons were rearranged to make them easier to understand, tooltips added to dialogs, angular range limited to actual range of tilt series.

* 2/28/10: Fixed an initialization problem in beadtrack (present since 3.12.5) that throws off tracking in some cases.

* 2/26/10: Made Tilt do subtractions for both reconstruction and reprojection in SIRT that cannot be done internally, and to put out statistics that are gathered in the finish log of a SIRT run.

* 2/21/10: Rewrote Sirtsetup in Python to use internal SIRT in Tilt where possible, to leave and convert reconstructions at specified iteration numbers, and to not split the command file up when going to only one processor.

* 2/5/10: Fixed problem with Ccderaser removing way too many points in data with low counts starting at -32768 (i.e., from FEI software).

* 12/10/09: Tomostitch has new options to allow stitching to be done with binned volumes then repeated with unbinned volumes; it adjusts parameters as appropriate. It also automatically updates a warping patch file from a model that has been edited.

* 11/21/09: Tiltalign now reports the mean residual for each contour (fiducial) in the table of 3D positions.

* 9/8/09: Added Fitpatches to do linear and local fitting on patch vectors in supermontage overlap zones and manage patch files and vector models when edited.

* 9/7/09: Made Stitchalign able to eliminate vectors if they are not present in all the versions of a patch file managed by Fitpatches, and if they are outliers or had high residuals in fits in Findwarp.

* 9/2/09: Fixed residual outputs into patch files from Refinematch and Findwarp; residuals were being assigned to the wrong vectors.

* 3/17/09: Added option to Tiltxcorr to enter an angle offset, which can sharpen correlations at high tilt when the specimen is tilted at 0 degrees.

5/26/10: Fixed alignlog -a output to exclude local area results.

5/24/10: Made cleanup before and after parallel Tilt much more restrictive to avoid deleting data sets named tilt-n.

5/24/10: In Tilt, fixed centering of vertical slices with large Y offset/ X axis tilt, fixed handling of fill value for output in internal SIRT.

4/27/10: Stopped Ctfplotter message about inconsistencies when there is no existing defocus file.

4/7/10: Fixed problem with edgepatches calling corrsearch3d with mins/maxes numbered from 0.

4/2/10: Fixed initialization problem in Ctfphaseflip's detection of bad view numbers and fixed the warning when a simple one-line file is used.

4/1/10: Fixed bug in Ctfplotter that was putting out views numbered from 0 and made Ctfplotter and Ctfphaseflip detect erroreous view numbers in a defocus file and adjust them up by 1.

3/30/10: Fixed backup directory entry to Copytomocoms to preserve spaces.

3/18/10: Fixed Sirtsetup conversion of first srec file being left.

3/8/10: Changed Ctfplotter so that noise config file can have relative paths.

3/8/10: Added option to inform Findbeads3d of binning.

12/29/09: Fixed Makejoincom to avoid problem with entry output from rotatevol.

11/25/09: Transferfid now allows pixel sizes of two axes to differ by 2.5%.

11/2/09: Fixed bug in Edgepatches when it had to reduce patch thickness.

10/27/09: Fixed setupcombine to clean up files with find due to a change in tcsh in RHEL5.

10/15/09: In Tilt, fixed reprojection from model when there is a single X axis tilt and untilted slices are computed. Points at high tilt were miscentered. also fixed incremental mode when untilted slices are being computed.

10/9/09: Fixed some problems with solving for thinning in Tiltalign.

10/7/09: Fixed mean value used for masking in Tiltxcorr and added output of raw peak strength.

9/14/09: Made Stitchalign vary metro factor when search fails.

9/2/09: Added ability for Refinematch to put out the residual vectors as reduced patches, and for Findwarp to put out the fraction of fits in which each patch is an outlier. Patch2imod will store the outlier fraction in the model and Imod2patch will output it to a new patch file.

8/14/09: Fixed power option in densnorm.

8/4/09: Fixes for SIRT: fixed Splittilt to use a different boundary info file for reprojection; fixed Sirtsetup to pass the boundary parameter properly and to detect last reconstruction correctly; fixed parallel writing in the reprojection.

6/25/09: Changed Tilt to allocate its memory and added a temporary option to specify the memory size.

2/24/09: Colors changed so grid appears when printing from Ctfplotter.

Changes in General Processing Programs or Infrastructure

** 12/10/09: Flattenwarp can smooth surfaces by fitting thin plate splines, can output a model for visualizing the surfaces and picking the right smoothing, and can accept models of gold beads based on either Tiltalign or Findbeads3d output. A new program, Sortbeadsurfs, is provided to process such models before running into Flattenwarp.

** 6/14/09: Rotatevol, Matchvol and Warpvol were improved by: converting to Fortran 95 and using dynamic memory allocation, where the array size can be set by the user; setting up rectangular input and output volumes to use memory and read from disk more efficiently; computing data within cubes and cubes in a more efficient order; parallelizing with OpenMP.

** 1/6/09: Added Flattenwarp, a program to produce warping transformations for flattening a volume.

* 1/8/10: If the machine list to processchunks is a single number, it is interpreted as the number of processors to use on the local host.

Modified Findwarp to put out a warp file with missing transforms so that filling in and extending transforms is done only once, in Warpvol.

* 3/31/09: Tif2mrc and 3dmod will both read grayscale TIFF files with multiple samples per pixel by treating each sample as a separate image. When a multipage TIFF file has multiple image sizes, the smaller ones (e.g., thumbnails) are now ignored. Mrc2tif now writes data using libtiff and supports compression options.

* 2/15/09: Added structure for avoiding artifacts when writing to one file from multiple computers, implemented it for Tilt/Splittilt and Ctfphaseflip/Splitcorrection. ALL MACHINES USED FOR PARALLEL PROCESSING WITH DIRECT WRITING MUST BE UPGRADED TOGETHER.

* 2/15/09: Added options to Alterheader to set pixel spacing from pixel size in FEI/Agard style extended header, and to invert sign of origin. Wrote proper man page for Alterheader.

* 1/15/09: Port to Qt 4.4 of all Qt-based programs.

* 12/22/08: Blendmont uses a new method of padding for cross-correlation to reduce artifacts, and has an option (activated with VerySloppyMontage) to evaluate multiple correlation peaks with a real-space correlation coefficient computed from filtered images.

5/26/10: Added check to mtffilter for padded volume > 2 gigavoxels.

1/14/10: Fixed problem created 1/5/10 with matchvol/warpvol/rotatevol.

1/8/10: Converted Taperoutvol to PIP input and added an option that sizes should not be increased to be suitable for FFTs; added same option to Tomopieces and Chunksetup so NAD chunks can be run with no padding at all.

1/6/10: Made install script copy DLL's out of Microsoft folder into bin for Win2K, added warnings for 64/32-bit mismatch on Linux and Mac.

1/5/10: Fixed problem with Matchvol not making input array large enough

12/28/09: Fixed tomopieces to suppress entry output, which crashed setupcombine.

12/7/09: Made Processchunks responsible for echoing CHUNK DONE at the end of every command file; stopped it from overwriting a sync log with CHUNK DONE.

12/5/09: Added option to Warpvol to scale transforms to apply to a volume at a different binning; fixed half-pixel shift in Warpvol and Matchvol when image size is odd.

11/21/09: Clip has an option to number Z values from 1 and options for clip stat to mark slices with min and max values that are outliers.

10/14/09: In Extractpieces, Extracttilts, Extractmaggrad, and Newstack, switched to allocating arrays for extra header data.

10/14/09: Fixed a problem with Corrsearch3d (no patches fit within constraints) when no transformation or shift was specified.

10/12/09: Added option to Xfsimplex to measure difference or correlations in patches, to save having to do low frequency filtering.

10/9/09: Added option to Newstack to taper image as in Mrctaper.

10/8/09: Changed startup scripts for Linux and Mac to put IMOD man pages on the MANPATH if it exists.

10/7/09: Changed Flattenwarp to allow separate binning in X/Y and Z.

9/16/09: Xyzproj modified to make projections suitable for common line analysis and to make simple vertical projection more efficient.

9/8/09: This time thread number really will be controlled by OMP_NUM_THREADS.

9/7/09: Switched centering of transform in Xfsimplex to conform to centering in interpolation routine.

8/17/09: Added variant of PBS queue type for getting load under Maui.

8/4/09: Implemented ability to read DigitalMicrograph stack files with dm2mrc and 3dmod, allowed dm2mrc and raw2mrc to work with filenames starting with dash, fixed problem with dm2mrc accessing files not in current directory, and removed -d option and cleaned up dm2mrc man page since all files are scanned.

6/22/09: Changed cubic interpolation so thread number is controlled by OMP_NUM_THREADS.

6/22/09: Fixed mrcx for 64-bit systems.

6/10/09: Fixed problem running Xfmodel to find transforms with PIP input.

2/24/09: Imodinfo -c option now reports a centroid based on line segments rather than enclosed area for open contour objects.

2/19/09: In Imodjoin, increased maximum size in model header to hold new joined model so whole model can be viewed in Zap window. In Remapmodel, adjusted maximum Z to hold remapped Z values.

2/15/09: Added details on the contents of the extended header and commands for extracting data to Header program output.
