Understanding duplication level

[lalalagartija]

Hi,
I want to use metaquast to evaluate the chimerism of my contigs. Could you help me find the best options so I get a good view of my chimerism (if the contig has several different phylogenetic markers or duplicated single copy markers) ? I don't completely understand the duplication level given in the output because it is / species and not per contig. If several contigs match a similar species will it count as duplication ? Can't it be just the evidence for natural heterogeneity ?
Thank you very much,
Sofia
