We still maintain legacy docs for EMAN1, though it is no longer supported. Best practices in the field have changed considerably since the last update to EMAN1, and we can no longer recommend it for single particle reconstructions due to the lack of "gold standard" resolution measures, and other necessary validations. Unlike EMAN2.0x, EMAN2.1 has abandoned the problematical BDB system, and has many other improvements to make it as easy to use for both beginners as well as advanced users, and we strongly encourage users to upgrade.
