Dear Colleagues: OOF2 2.0.4a1 is now available on the OOF2 website, at http://www.ctcms.nist.gov/oof/oof2/. This is an alpha release, meaning that it hasn't been thoroughly tested yet. However, users interested in loading Orientation Imaging Microscopy data into OOF2 are strongly encouraged to install 2.0.4a1 and to send us feedback. More information on the OIM features is available at http://www.ctcms.nist.gov/oof/oof2/oof2oim.html. In addition to the new OIM features, version 2.0.4a1 contains a few other new features and bug fixes, which are documented at http://www.ctcms.nist.gov/oof/oof2/changes.html. Please send us feedback on the new version. Comments and suggestions on OIM handling will be especially appreciated. Sincerely, The OOF development team
