[Gretl-devel] problem with large gdtb panel datafile and index variables

Hello once more, I'm seeing a problem handling a fairly large panel dataset in the GUI. It started with a ~200MB binary gdtb file that was a recognized panel, with index variables "iso" (time, iso dates) and "STATIONS_ID". This had lots of unneeded obs with mostly missings, so I saved a reduced version of the dataset (after "smpl --no-all-missing <somelist>"), yielding a file with about 100MB. As expected (?), the official panel structure was lost there, so I wanted to re-instate it, using the nice GUI dataset structure tool. Basically, this ended up in a non-responsive gretl which had to be killed by the OS. (I waited several minutes before doing that.) In contrast, doing "setobs STATIONS_ID iso --panel-vars" in the console worked quickly. (I only had to manually re-add the panel time information, which was suboptimal, but not a real problem.) Maybe worth mentioning, the dataset is hugely unbalanced, which also affects the STATIONS_ID index variable, I believe. But if that were important, it's not clear why it works in the console... thanks sven
