UnboundLocalError: local variable 'my_matching' referenced before assignment

Hello,

I have managed to run metacoag on 9/10 flye-based nanopore assemblies, but I get the following error on one of my samples: Is it maybe related to the low number of contigs with marker genes?

nohup sh -c 'ls assemblies/|while read sample;do mkdir -p metacoag/$sample && metacoag --assembler flye --graph assemblies/$sample/assembly_graph.gfa --contigs assemblies/$sample/assembly.fasta --paths assemblies/$sample/assembly_info.txt --abundance abundance/${sample}.tsv --output metacoag/$sample;done'
