Reconstructing ancestral change History by accomodating dates and locations info

[ISskandaR]

Hi dears, I'm facing an issue in reconstructing ancestral history change, actually I'm trying to perform a phyolgeographic analysis with discrete traits according to < https://beast.community/workshop_discrete_diffusion > by accomodating dates and locations travels according to (https://beast.community/travel_history.html). I customized the XML file as described in the above mentioned links and I used the customized Beast version available at https://beast.community/tutorials/travel_history/files/beast_travel_history.jar . Unfortunately even by strictly following the sample XML format available at https://beast.community/tutorials/travel_history/files/9seqs_travelHistory.xml (taking in account any differences in between the inputs ) I did not succeed ; after my best try I got the following message :

I'd appreciate any kind of support Best regards
