Dear all, I found a minor bug when i imported Eviews's files of panel data to gretl. You may see the attached two files. The one named "test-dated-panel1.wf1" can be imported into gretl correctly. The other named "test-dated-panel2.wf1" has a problem in importing to report an error message: Error reading workfile header I did some testings and guessed that it might be due to that Eviews allows the "time-period" dated for starting from integer "0" while gretl only allows for non-zero positive integer.
