Hi everyone. I'm starting my bioinformatics analysis. I have never worked with Linux, so I have some difficulties.
My goal is to compare a nitrogen fixing bacterium genome with the reference genome of this same bacterium.

I used the following commands:
mummer -mum -b -c B_SEMIA_5080.fasta Bradycontig.fasta > BradyM.mums

To build the graph I used the command:

mummer --postscript --prefix=BradyM BradyM.mums

But Linux returns me with the following message:
Can't use 'defined(%hash)' (Maybe you should just omit the defined()?) at /usr/bin/mummerplot line 884.

Please, can anyone help me?
