Metaplasmidspades cli using assembly graph

[pbelmann]

Thank you for developing Metaplasmidspades!

I`m using the following command to run Metaplasmidspades and I have two questions.

metaplasmidspades.py --assembly-graph test1.gfa --12 test1.fq.gz --only-assembler -k 141 -o out_graph6

I would like to reuse the assembly graph build by megahit as input for metaplasmidspades.
The k-mer length used in the graph is 141 which is impossible to provide as input for metaplasmid spades
because it tells that only k-mer length values between 1 and 127 are allowed. Is there any way to change this setting?

Is it intended that one must use --only-assembler when using --assembly-graph? I did not found this in the documentation.
I'm using this setting after reading the error report that is produced when running metaplasmidspades without --only-assembler:

== Error ==  to run read error correction, reads should be in FASTQ format (.fq, .fastq, .bam, .fq.gz, .fastq.gz are supported): /test/test1.gfa (single reads, library number: 1, library type: assembly-graph)

Correct

There is no way to do this without recompiling SPAdes from source. Also note that this is completely unsupported configuration, so unexpected bad stuff might happen
