plot_slopes_by_location in Geolocator Discussion & Support Posted July 18, 2018 Hi all, Following Eldars advice above I was able to get the other units to work using the calibration of another geo (Thanks again Eldar!). I'm still having difficulties with this one unit and i'm not really sure why. Whenever I run this unit through FlightR it appears that the bird never returned to the breeding ground in the 2010 season, which is possible since we never relocated or captured it, I just think that it's highly unlikely. My first thought was that this unit contains two years of data so I tried splitting it. Once the unit was converted into TAGS format I tried splitting the data in half to make it similar to a geo that had a single year of data. This seemed to work slightly better than trying to run it as a single unit, but the results were still scattered everywhere. All of these failed attempts I was using a different geo for the calibration, I cant run the calibration otherwise. I'm not sure what else to do, any advice would be greatly appreciated!
