Attribute error?

[mht85]

Hi,

I mapped my RNA reads to my assembly with Hisat2 and fed it into BESST_RNA. However, I got the following error.

---

Starting scaffolding with library: DARW_heart.hisat2.sorted.bam Parsing BAM file... Computing parameters not set by user...

Any ideas or solutions would be much appreciated.

Thanks Mun
