Download EMAN

current version 1.0 beta1

released 1/10/2000

This is a BETA release. That means it may have a some bugs, and significant changes may still occur before the release version. That said, it does work, and has sucessfully been used on at least 7 molecules. Please contact me if you run into a specific problem that's not on the known bugs list. Happy reconstructing.

Once you've installed it just run 'eman' and press the 'step1' button. This will guide you through the reconstruction process.


Binary Versions

Compiling EMAN is still a bit of a pain, although everything is included in the source package now. Use a binary if you can.

SGI - IRIX 6.5

(use the shift key when you click on the link)
download eman1.0b1.sgi.tgz.

SGI - IRIX 6.2

(Sorry, we don't have any way to compile for earlier IRIX versions any more)

Linux - x86 - libc6 - redhat 6.0

dowload eman1.0b1.linux.tgz.

Alpha - Tru64 Unix (linux with support libs)

This version has been temporarily removed because it doesn't work properly. It will return when I can figure out what's going on...
 

To install the binaries:

That's it. If you need to uninstall, just '/bin/rm -rf EMAN' in your home directory. EMAN uses the QT library and the fftw library. The versions used to compile EMAN are included in the lib directory. A binary of a href=http://www.ssec.wisc.edu/~billh/vis5d.html>Vis5d is also included. Please note this is for your convenience only, and this is a separate product written elsewhere. Please follow the link for usage info.

Source

EMAN may be somewhat difficult to compile. I've included all of the necessary library distributions in the source archive now. There's also a makefile which should work under linux, alpha (Tru64) and IRIX (SGI). 'make linux' will also work on linux-alpha, however, due to known optimization problems with the gnu C++ compiler on Alpha's, resulting code will be 3X slower than code compiled with digital's compiler. It is possible to run the Tru64 binaries under linux, but some support libraries need to be copied (contact me for details).

Download the source archive (quite large) eman1.0b1.src.tgz

Unpack this archive in your home directory. 'tar -xvzf eman1.0b1.src.tgz' will do it if you have GNU tar installed. Otherwise, 'gzip -d eman1.0b1.src.tgz' and then 'tar -xvf eman1.0b1.src.tar'.

'cd EMAN/src', then read the README.FIRST file.

Let me know if you need to change anything to get it to compile on your machine. Good luck !!!


Here is the data set used in testing the program as described in our paper (submitted JSB June 1999). It is QUITE large. Don't download it unless you really want it.

BTV.test.tgz


Y2K Compliance

EMAN does not rely on time/date information for any of its processing, and therefore isn't susceptible to Y2K problems. The only place where dates are used in this software are in the log files for informational purposes. In these places, EMAN uses 4 digit years computed with the standard Unix clock mechanism which is reliable until at least the year 2038, in some cases 2106 (depending on the machine). This standard is expected to be updated in the near future. Even in 2038, the operation of the software will be unaffected.
