The Questions:

Installing EMAN:

1. [:EMAN1/FAQ/GUI1:I installed EMAN 1.8, all command line programs work OK. But if I run GUI program, it gives me error: "error while loading shared libraries: libXinerama.so.1: cannot open shared object file: No such file or directory "?]

2. [:SELinux:After I installed EMAN 1.8 on Fedora Core 6, I get this error message when I type eman: "EMAN/lib/libqsci.so cannot restore segment prot after reloc: Permission denied"? ]

3. [:CMAKE1:I am trying to install CMAKE from source, but I only get three program cmake, cpack and ctest, I do not have ccmake. But no error message in compilation process. What am I missing here? ]
4. [:EMAN INSTALLER1:I download the EMAN 1.8 binary for linux, the file unpacked fine, but the installer does not seem to run. It returns immediately and print out message like this: "Please add the following line to the end of your /home/gtang/.bashrc: source /home/gtang/EMAN/eman.bashrc." Is this normal?]
5. [:EMAN QT4:Can I compile EMAN with qt4?]
6. [:EMAN FFTW3:Can I compile EMAN with fftw3?]

7. [:EMAN FFTWGEL:What is fftwgel, should I use it instead of fftw2?]

8. [:Ubuntu baddevice error:I build eman on my Ubuntu 7.04, when I type 'eman', before the window shows up, I see the error message dispalys 'X Error: BadDevice, invalid or uninitialized input device 169'. I installed the binary release for Ubuntu, the same thing happens. What is it?]

Using EMAN:

1. [:EMAN1/FAQ/Dvd2007:I want to learn how to use EMAN, where can I get some sample data to try a reconstruction ?]

2. [:EMAN1/FAQ/Heterogeneous:I have a good reconstruction, but my data is heterogeneous. How can I separate my data to better process it ?]
