Dear Everyone, I am a complete beginner to this field and to this software, so please forgive me if I ask something stupid. I am using Ubuntu 12.10 64 bit. Demeter was built from source following the guidance here: http://bruceravel.github.com/demeter/pods/installation.pod.html Ifeffit was also built from source before the installation of Demeter. I tried to run dathena from a terminal and import a data file download from here: http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/examples/data.html http://cars9.uchicago.edu/%7Eravel/software/doc/Athena/html/examples/data.ht... Dathena said that the data file is not readable (see the attached screenshot). No output text appeared on the terminal. If I use the old version of Athena installed from the repository of Ubuntu, the data file can be read easily. The data file is also attach. Could you please explain me about this issue ? Thank you very much in advance. Best, Khuong Huynh
