Error in running the tool: Input tree error #93

Hi, I want to run Astral for my dataset. But when I execute the command, I am getting this error.

This is ASTRAL version 5.7.8 Gene trees are treated as unrooted Exception in thread "main" java.lang.RuntimeException: Empty name observed; likely, an input tree has an error at phylonet.coalescent.TaxonIdentifier.taxonId(TaxonIdentifier.java:33) at phylonet.coalescent.CommandLine.readInputTrees(CommandLine.java:797) at phylonet.coalescent.CommandLine.readOptions(CommandLine.java:321) at phylonet.coalescent.CommandLine.main(CommandLine.java:486)

What is the reason for this and how can I resolve it.

Many thanks, Upendra

You probably were running with multi-alignment file, not a tree file. You need to generate a tree with raxml-ng or something before you run ASTRAL with the tree.
