• 20 DEC 2022  Release of BrainVoyager 22.4.4. BrainVoyager 22.4.4 is a patch release fixing an important coregistration issue of 22.4 that resulted in sub-optimal fine-tuning alignment when using FMR documents with non iso-voxel sizes (datasets using iso-voxel sizes are not affected by this issue). To prevent the creation of VTCs that do not fit well to the coregistered VMR space, this patch release is highly recommended for all users. You can download the patch release from the "Downloads" section of the BrainVoyager web site (https://www.brainvoyager.com/downloads/downloads.html). We also highly recommend users of BrainVoyager 22.2 to upgrade to the 22.4.4 version to avoid a severe issue in case one uses trilinear interpolation when creating MNI VTC files combined with the new bounding box fitting option (this issue does not occur when using sinc interpolation in the 'Create VTC Options' dialog; BV 22.4 releases are not affected by this issue).

• 03 MAY 2016  Issue with FMR-VMR fine-tuning alignment in BrainVoyager v20.0 / BVQX 3.0. When running the FMR-VMR coregistration tool, the default fine-tuning alignment step does not perform well in this version. Since the header-based initial alginment works properly, this usually leads only to small deviations when visualizing functional data in subsequently created VTCs with respect to anatomy. We nonetheless strongly suggest to follow the suggestions below to avoid the problem in the future. To be on the safe side, we also recommend to re-analyze data that has been processed with the default FMR-VMR fine-tuning adjustment tool of the 20.0 version (earlier versions are not affected). We apologise for any inconvenience this may cause.
  
  How to fix the issue in current version? Since BrainVoyager provides alternative fine-tuning coregistration procedures, the issue can be solved in the current version by selecting the "Intensity alignment using multi-scale approach" option (instead of the default "Gradient-based affine alignment" option) in the "Fine-Tuning Alignment" tab of the "FMR-VMR Coregistration" dialog.
  
  Upgrade to version 20.2 The issue is fixed in BrainVoyager 20.2 / BVQX 3.2 that will be released in the next days and announced in this document and via email. Besides fixing the gradient-based fine-tuning alignment tool, the new version also provides a new boundary-based registration (BBR) tool that produces optimal alignment results.

  Real-time volume rendering support. The new hardware-accelerated volume renderer does not work with all graphics cards since it requires advanced features such as the GL Shading Lanugage (GLSL) and advanced texture float buffers. When prerequisites are not met (check the Log pane), the program usually offers running a (much slower) software-based version of the volume renderer. Some users have reported that the program crashes when attempting to use the hardware-accelerated version. To enable using at least the software-based version in these cases, we will offer a switch that forces using the software renderer in the next maintenance release. Furthermore, we want to post a list of supported and unsupported graphics cards and invite you to send us a short email whether hardware-based rendering does (not) work on your system; we recommend to compose an email using the new "Submit Bug or Suggestion" item in the "Help" menu since that will also provide us with information about the used operating system.

• 01 MAR 2010  Release of BrainVoyager QX v2.1.2. BrainVoyager QX 2.1.2 is a maintenance release providing several important bug fixes and its installation is recommended for all users (use installers posted at the "Downloads" page of our web site). The most severe bug that has been addressed is a bug in the VOI center-of-gravity table that could occur when VOIs of subjects were defined with a VMR that was not in Talairach space (e.g. an averaged brain not marked as "TAL"). For details, as well as for a description of other fixed bugs and enhancements, see the updated 2.1 release notes.
  This release also includes the GCM Plugin that was missing in previous 2.0 / 2.1 releases. Besides cross-platform compatibility (it runs now on 32 and 64 bit Windows, Mac and Linux), the plugin has been updated to handle the new VTC format, i.e. VTC files may contain 4-byte float or 2-byte integer data.

• 04 FEB 2010  Release of BrainVoyager QX v2.1.1. BrainVoyager QX 2.1.1 is a maintenance release providing several bug fixes and its installation is recommended for all users (use installers posted at the "Downloads" page of our web site). The most relevant bug that has been addressed is the "Zero covariance matrix in fitting routine" issue that was reported by many users; this message could appear at the end of motion correction and required re-running pre-processing. While this usually worked fine, users did not know whether this really fixed the problem. Inspection of the error showed indeed that the data is processed correctly in case that the message does not appear so no re-processing of data is necessary. Nonetheless, the bug is annoying, especially when running scripted analyses. It turned out that the underlying problem was actually not located in the motion correction routine but occured sporadically in the slice scan time correction routine when using spline interpolation (default). This problem has been fixed in the 2.1.1 release.
  The 2.1.1 maintenance release also fixes some other issues providing better processing and integration of functional and anatomical data sets with non-standard image dimensions.

• 28 AUG 2009  Release of BrainVoyager QX v2.0.8. BrainVoyager QX 2.0.8 has been released to correct bugs detected in version 2.0.7. One bug (detected on 27 AUG) concerns FMR preprocessing and is classified as critical since its full correction requires likely redoing the preprocessing. The problem occured in versions 2.0.7 (and 2.0.6) in case that several FMR preprocessing steps were selected in the "FMR Preprocessing" dialog and performed in one go; in this case, the final peprocessing result does not always contain the results from all performed preprocessing steps, but contains only the result of the last performed preprocessing step. If, for example, spatial smoothing and high-pass filtering are selected, the resulting preprocessed data might only reflect the high-pass filtering but not the spatial smoothing step. This problem did not occur when single preprocessing steps were performed or when using scripted preprocessing. This issue has been fixed in 2.0.8 and we strongly suggest to switch to the new version to avoid the problem in the future. To be on the safe side, we furthermore recommend redoing FMR preprocessing with the 2.0.8 version for those FMR/DMR files that were preprocessed with version 2.0.6 or 2.0.7. We apologise for any inconvenience this may cause.
  The 2.0.8 maintenance release also fixes some other bugs including an issue with VMR averaging and a problem with specifying the size of patches for time course selection on meshes. These bugs are described in more detail in the updated release notes in the section "Bug Fixes". Furthermore, the updated installer will install all available plugins correctly - in the previous version, some plugins did not show up in the "Plugins" menu on some platforms.

• 3 JUL 2009  Release of BrainVoyager QX v2.0.7. BrainVoyager QX 2.0.6 has been released in mid-June. While we received largely positive feedback, there was one issue reported with the "rename DICOM" tool, which would simply not rename some data sets. This issue has beenn fixed and a new patch release (v2.0.7, build 1470) has been made available. Another minor improvement concerns MVPA tools: it was not stated in the documentation of 2.0.6 that the MVPA trial estimation step requires protocols in "volume resolution"; this info has been added in the User's Guide and the program also presents a respective message box when running the tool with "millisecond" protocols. In order to avoid the "rename DICOM" problem and for other minor improvements, we recommend to update to the latest program version.
  The Mac 64-bit version currently suffers from a major GUI problem preventing editing data fields in some widgets; this issue is not due to our code and has been filed as a bug report to the provider of the used GUI tool (Qt software, Nokia). Until this issue is fixed, we recommend using the 32-bit Mac version.
