Fatal exception: Cannot invoke "dr.evomodel.tree.TreeModel$Node.getHeight()"

[Leliana42]

Hello,

I'm Trying to run BEAST v1.10.4 but it terminates with an error and I get this error message :

"Fatal exception: Cannot invoke "dr.evomodel.tree.TreeModel$Node.getHeight()" because "< local2 >.rightChild" is null java.lang.NullPointerException: Cannot invoke "dr.evomodel.tree.TreeModel$Node.getHeight()" because "< local2 >.rightChild" is null at dr.evomodel.tree.TreeModel$NodeHeightBounds.getLowerLimit(Unknown Source) at dr.evomodel.tree.TreeModel$NodeHeightBounds.getLowerLimit(Unknown Source) at dr.inference.model.CompoundParameter$CompoundBounds.getLowerLimit(Unknown Source) at dr.inference.model.CompoundParameter$CompoundBounds.getLowerLimit(Unknown Source) at dr.inferencexml.operators.ScaleOperatorParser.parseXMLObject(Unknown Source) at dr.xml.AbstractXMLObjectParser.parseXMLObject(Unknown Source) at dr.xml.XMLParser.convert(Unknown Source) at dr.xml.XMLParser.convert(Unknown Source) at dr.xml.XMLParser.convert(Unknown Source) at dr.xml.XMLParser.parse(Unknown Source) at dr.app.beast.BeastMain.(Unknown Source) at dr.app.beast.BeastMain.main(Unknown Source)"

I don't know what is the problem, I'm used to having poorly formed xml files but this time it seems like it isn't the same kind of error, as "dr.evomodel.tree.TreeModel$Node.getHeight()" and ".rightChild" doesn't appear in the XML file. I don't know what they are and how to fix this. (The tutorials files run normally)

Please help and thank you in advance

The error message suggests a missing right child of an internal node on the tree. You might want to check the starting tree if you provided any starting tree topology. You could also share a xml file that could replicate this error (where you could replace the real sequences with fake ones if that is a concern) so that I could take a look.

Without an XML it is not possible to investigate this issue.
