[Gretl-devel] Re: saving gdtb: gretl retains old extension

Hi,
another minor glitch: I had a large Stata dta file and imported it into
gretl - this actually worked flawlessly via dragging-and-dropping (on
Windows). Then I went on to save it; in the save dialog gretl inserted
the extension "gdt" automatically, and when I changed the format to the
binary gdtb type in the drop-down box at the bottom, in the end I had a
file ending in .gdt.gdtb.
Obviously very easy to correct manually in various ways along the steps
taken, but maybe now we want to shake out even minor stuff like this.
Hm, I'm observing something strange with this conversion to gdtb, and
using the choice of "new missing codes".
[BTW I don't remember exactly, does the compression level actually apply
to the gdtb format? I get a file size of 25900KB no matter whether I
choose 0 or 1 for that level.]
Opening this 26MB file causes a very noticeable delay of several
seconds. OK, the PC is not brand new, but hey... This is a panel dataset
with 26 time periods and roughly 18000 units. I somehow seem to remember
that the gdtb format was introduced because of speed, and indeed it felt
much faster back then (but not with this very same dataset, admittedly).
thanks
