Introduction

softWoRx version 7.0.0 is a major release providing improved functionality and increased reliability.

Changes and Additions

Software Environment:

• All of the softWoRx software components running on the workstation are 64-bit applications.
• Shared memory sizes may be set much larger (15Gb) due to 64-bit memory addressing.
  
• The DeltaVision file format has been expanded to include a "Panel" dimension to better accommodate plate scanning and multi-panel acquisition.

Acquisition (Resolve3D):

• Paneling is available for experiments with Z Sectioning, Multiple Channels, Time Lapse, and Point Visiting.
  
• Time Lapse imaging honors a per-channel Frequency setting for regular channels and Reference Image channels.
  
• A Multi-Channel Reference Image capability has been added to the Experiment Design.
• Stage View is now moveable and resizable.
• Stage View thumbnails now have a resolution factor that can be specified in Settings.
  
• Stage View thumbnails can be adjusted for brightness.
• Image Scan Sequence may be specified for Fast or Conventional imaging modes.
  
• Fields of View in Plate Scan experiments now use the file format's Panel dimension, so separate files for fields are no longer required.

DeltaVision Processing Capabilities:

• The Deconvolution tool has been improved to manage much larger images and provide more rapid convergence for enhanced ratio deconvolution.
  
• Task Builder Process Chains may now be saved to be opened later.
• Stitching has been added to the Task Builder.
  

OMX Processing Capabilities:

• A new robust OMX Image Alignment method has been added. Earlier tools are still available in a "Legacy" submenu.
• OMX Image Alignment Calibration plots markers on the input grid image to indicate where usable alignment points are found.
  

Software Defects Fixed

• DeltaVision Acquisition: Panel experiments may now be created  with one row or one column.
• DeltaVision Acquisition: Deconvolve During Time Lapse experiments can now work along with experiment Post-Processing tasks.
• DeltaVision Acquisition: The Point List now properly updates Z coordinates after running an experiment with UltimateFocus.
• DeltaVision Acquisition: Stage View thumbnails no longer disappear when the lower left hits the left and bottom borders of the view.
• DeltaVision Acquisition: Size requirements for a Plate or Point Visit experiment are calculated correctly and updated during the experiment.
  
• OMX Image Registration: The aligned image file no longer gets corrupted when Z offsets are set to the same non-zero value.
• OMX Image Registration: Intensity Mean values are now correct for images with Z shifts specified.
• OMX Image Registration: Shift and Rotate method now works properly from the Task Builder.
• OMX Image Registration: The "most-recently used" parameter files ar now being properly remembered by the software.
  
• OMX Generate Widefield: This tool no longer fails when specifying a Z subset.
  
• Arbitrary Profile: The Full-Width Half Max calculation has been improved.
• Stitch: The interactive Stitch tool now has status reporting and Cancel functionality.
• Stitch: Enabling Remove Bright Pixels no longer causes the tool to crash.
• Convolution: Crash when re-using the tool has been fixed.
  
• Edit Polygon: Closing the input Image Window is now properly handled.
  

Known Problems and Workarounds

• Rotate3D: The Rotate3D tool may crash or produce unexpected results. If Rotate3D is critical for your workflow, it is recommended that you not install this update. The problem will be fixed in the next minor release of softWoRx.
  
• DeltaVision Panel File Format: Images collected using the Panel or Plate Scan (with multiple panel sites) capabilities in Resolve3D are not compatible with softWoRx versions older than 7.0.0. If these files are stitched on a system running 7.0.0 or later, they may then be used with older software.
  
• DeltaVision Acquisition: The Fast Acquisition state can interfere with running a time-lapse Plate Scan experiment. If Fast Acquisition is toggled On and the Conventional Time Lapse Fast Acquisition Option is toggled Off, only one time point will be collected.
  
• Workaround: Toggle Plate Scan Off temporarily (which enables the Fast Acquisition check box), switch Fast Acquisition Off, then switch Plate Scan back On.
  
• Image Buffer Overwrite: When using the sCMOS camera during a fast acquisition experiment with the Entire Scan shutter mode enabled (the fastest frame rate mode) and using a combination of large image sizes (1k x 1k and larger) and very short time lapse values (< 5 ms), it is possible that the instrument controller may not be able to process the acquired images from the memory buffer fast enough. When this happens, an image on the buffer waiting for download is overwritten with a new image. The new image is then captured as the image for the previous timepoint.
  • Workaround: Reduce the frame rate by using longer time lapse values, reducing the image size, or reducing the number of timepoints.
  Image Window (Copy/Paste Scale): If a "copied" set of display scale values exceed the Minimum and/or Maximum values in the image to which the values are "pasted," the scale values will be truncated to fit within the Minimum/Maximum range. 
• Workaround: Manually type the values into the Min/Max/Exp field of the Scale tool belonging to the window that will contain the pasted values.
• Image Window (Save...): If one or more of the channels is toggled Off in the Save tool, incorrect scaling of the output image may result.
• Workaround: Use the Copy Region tool from the main softWoRx menu bar and send the output to a file instead of a window.
• softWoRx: It has been reported that individual user accounts seem to lose permission to run softWoRx. 
• Workaround: A possible workaround is to remove (or rename) the file "user.swrc" in the .softworx_<hostname> subdirectory of the user account's home directory.
• softWoRx: Some older softWoRx versions or 3rd-party analysis tools can have difficulty with the latest softWoRx default data type.
• Workaround: Open the image with softWoRx and choose Save from the File menu of the image window. Choose Details..., and change the Data Type from No Change to 2-byte signed integer. Then, save a new copy of the file.
• Stitch: If you choose a subset of Z sections (from the Details... dialog), Stitch may fail.
• Workaround: Restart softWoRx and try again.
• Save As Movie: Saving a time-lapse image as a Movie when the window is in Montage By Time viewing mode may cause Save As Movie to crash. 
• Workaround: Try choosing the maximum that the image window time slider will go and specify that number for the End time in the Time: Start/End/Increment field of the Save As Movie tool.  Then, select Do It.
• Save As Movie: Using the Movie tool to play the window as a movie while Save As Movie is capturing images can cause the Image window to crash.
• Workaround: Pause all other movie tools prior to pushing Do It for the Save As Movie tool.
• Save As Movie: Attempts to save more than one movie at a time can cause crashes of either the Save As Movie tool or the Image Window that it is using.
• Workaround: Ensure any previous Save As Movie processes have completed before starting a new one.
• Align Image: This tool can be unreliable when it is used on a single-channel image.
• Workaround: There is currently no known workaround for this issue.
• Calibration File: Calibration files are created with the file name extension .dv_cal and may not be viewable in softWoRx by default.
• Workaround: Choose File -> Open from the softWoRx main menu and change the File Types filter from *.dv to *.
• Save As Movie: Graphical elements (like Line Profile graphics) are not accurately synchronized with the image data when movie frames are captured.
• Workaround: There is currently no known workaround for this issue.
• Deconvolution: Attempting to run two or more simultaneous multi-processor Deconvolution jobs on a multi-core workstation may occasionally cause severe slowing of all processing on the workstation. 
• Workaround: If this happens, cancel all but one of the jobs and allow it to complete before starting any further jobs.
