  <title>NITRC News Group Forum: cmtk-3.0-released</title>
  <link>http://www.nitrc.org/forum/forum.php?forum_id=4040</link>
  <description>We are pleased to announce the Release 3.0 of CMTK, the Computational Morphometry Toolkit (code name &quot;Cambridge&quot;).

This release fixes a number of major problems in earlier releases, specifically:

1. The handling of affine transformation matrices was broken, leading to incorrect derivation of transformation parameters from matrices. CMTK 3 continues to read existing transformation files exactly as earlier versions, but files created by CMTK 3 and later will be different.

2. The handling of image-to-space transformations in NIFTI files (qform and sform) was inconsistent with the NIFTI standard. CMTK 3 will continue to read existing NIFTI files in exactly the same way as earlier versions, but newly created files will differ.

See Release Notes for further details on changed behaviour.
