Issue about the assembled genome size about bridged and polished step

[linshengnan09]

Hi, I have assembled a plant genome with NECAT. The survey genome size is about 4.13g, but I got the bridged contigs was about 6.32g and the polished contigs was about 1.50g. Why is there a huge difference in genome laying after polishing? And Why the size of bridged contigs was 1.5 times the estimated size? Are two sets of haplotypes assembled?
the config file was compiled as it follows:
PROJECT=necat

Looking forward to your answer. Thank you!

Did you try removing the duplicates? e.g., purge_dups
