Dear Allin,

the error is still present.

What kind of other information is necessary in order to eliminate this bug?

Sometime ago there was a discussion about implementing some kind of automatic testing of Gretl, on Ubuntu 14.04 I can test the export/import functions with other programs (Stata, R, Python, Octave, Julia, not Ox).

Best regards,

Mihai

In the case that I run the script (gretl_export)from http://lists.wfu.edu/pipermail/gretl-devel/2013-April/004417.html in Stata the matrix is saved in the user director /home/acer.

This is on the same Ubuntu 14.04.
