Hello, dear community and developers! Please help me solve the problem of binding coordinates for visualization in auspice. I use Augur version 26.2.0 in Ubuntu. I use augur export v2 --tree refined\_tree.nwk --node-data traits.json node\_data.json --metadata metadata.tsv --lat-longs latlong.tsv --auspice-config config.json --output auspice.json command and all times i have this message from Terminal: WARNING: geo-coordinate file contains invalid line. Please make sure not to mix tabs and spaces as delimiters (use only tabs): Liaoning 41.2374106 122.9955469 and so it is for every case. I have rechecked the latlong.tsv file for delimiters many times. And there is definitely a tab used as a delimeter. I don’t know what to do anymore…

The lat-longs need an extra (first) field to represent the category (region, country etc). You can see a small example file [here](https://github.com/nextstrain/avian-flu/blob/18958650bef5a7ffa93ccc88f56867f45f5ccdc9/config/h5n1/lat_longs_h5n1.tsv) which we use for A/H5N1 avian-flu builds or the larger file we use as the defaults for `augur export v2` [here](https://github.com/nextstrain/augur/blob/master/augur/data/lat_longs.tsv)
