Help to identify the ploidy #92

Open Huyuxi08 opened 1 year ago

Huyuxi08 commented 1 year ago

Hi, Thanks for developing this great tool.

I'm trying to use GenomeScope 2 to identify the ploidy of two plant samples. The result of sample A indicates that it's a tetraploid. But the result of sample B is not that typical. If sample B is a tetraploid, is the reads duplication rate of these two samples that cause the difference in their GenomeScope plots? (The sequencing data of the two samples is the same, about 20G. ) 5F6FA29D-34B3-4C53-A5EE-ED42772C88B4

I agree sample A looks tetraploid. B is unusual. Is it from a single plant or a mixture? If it is mixed that can really complicate the analysis. Have you tried smudgepairs? That can sometimes help as well

Good luck!

Mike
