dnadiff throws an error

[MahshidF1991]

dnadiff throws the error message below

Building alignments
Error: Multiple query file is only supported with the SAM output format
Usage: nucmer [options] ref:path qry:path+
Use --help for more information
ERROR: Failed to run nucmer, aborting.

Here is how the dandify command is executed: ./dnadiff <ref.fna> <query.fna> where both ref.fna and query.fna are multi-fastA files.

It's worth mentioning that the common nucmer is executed smoothly.

Any insight on how to resolve the issue is very much appreciated.

Here is the output of dnadiff -version

./dnadiff -version
dnadiff 
DNAdiff version 1.3

and ./nucmer --version prints

./nucmer --version
4.0.0rc1
