| This page will be updated frequently until the final EMAN2.1 release. | '''NOTICE''' - projects in EMAN2.1 are not backwards compatible with EMAN2.0x due to the retirement of BDB. An upgrade program (e2projectupdate21.py) is provided to duplicate EMAN2.0x projects and make them 2.1 compatible, but it is strongly recommended that you NOT delete your 2.0x projects after conversion until you are sure that it worked completely. The conversion script has worked well in testing on our projects, but if you have done anything out of the ordinary, some files may not be automatically copied/converted. Please check the new project carefully after conversion, and delay deleting the original for as long as possible. The new project folder will contain an''info/' folder containing human-readable text files in ''.json'' format, instead of the old EMAN2DB infrastructure. Similarly, all of the image files will now be in .hdf files. Unlike BDB/EMAN2DB, these files can be moved, renamed, copied, etc as desired. |

An upgrade program (e2projectupdate21.py) is provided to duplicate EMAN2.0x projects and make them 2.1 compatible, but it is strongly recommended that you NOT delete your 2.0x projects after conversion until you are sure that it worked completely. === Major changes === * The BDB system has been completely retired for EMAN2 programs * (it is still possible to read BDB files, of course) |
