Hi, I am using Debian Testing (gretl 1.9.6 from official archives) and I installed X-12-ARIMA package from the main page: http://sourceforge.net/projects/gretl/files/x12a/x12a_0.3-3_i386.deb/down...: grzes:/home/ga/Downloads# dpkg -i x12a_0.3-3_i386.deb Selecting previously unselected package x12a. (Reading database ... 352205 files and directories currently installed.) Unpacking x12a (from x12a_0.3-3_i386.deb) ... Setting up x12a (0.3-3) ... I restarted gretl, however the command "X-12-ARIMA is still greyed out" - I tried data3-6.gdt example. What am I doing wrong and how can I fix it? Cheers, Grzegorz
