Gc-assembler outputs nothing


I generated DAA file with diamond and generated .rma file with MEGAN’s daa2rma utility. I then ran gc-assembler as follows:

`./gc-assembler -i ../../terrapin/reads_agassizii/reads2mitgenes.rma  -fun none -id ALL -t 16`

Here is the output log:

Version   MEGAN Community Edition (version 6.10.0, built 18 Oct 2017)

Loading MEGAN File: reads2mitgenes.rma

Peak memory: 10.1 of 10.7G

It did not generate any output FASTA file. Am I doing anything wrong while running the gc-assembler on command line?
