multiple overlapped snoRNA genes got annotated by maker

Jia-Xing Yue-2
Hello,

I configured snoscan (v.0.9.1) for my maker installation (v2.31.9) and run the annotation for a yeast (S. cerevisiae) genome. I think the annotation went well with regard to tRNAs and protein-coding genes but I am not sure about snoRNAs. I found multiple overlapped snoRNA genes were annotated by maker as the example below shows. I was wondering if this is expected. If not, what might have caused this problem and is there a way to work around. Thanks in advance!

Re: multiple overlapped snoRNA genes got annotated by maker

Hi Jia-Xing,

That has been my experience in the past as well. For the non-coding RNAs tRNA-scan is very accurate while snoscan seems to be quite sensitive but very specific. Did you give it a “snoscan_meth” file? Giving it a snoscan_meth file will help with accuracy. The biggest gains in accuracy are from small RNA-seq data. In the paper where we used snoscan on maize we didn’t keep any snoRNA predictions that didn’t have support from small RNA-seq data, in practical terms we got rid of anything with a AED of 1.

I hope this helps,
Mike

Re: multiple overlapped snoRNA genes got annotated by maker

Jia-Xing Yue-2
Hi Michael,

Many thanks for the information! I will specify the "snoscan_meth" file and give it another try then. I majorly want to use maker to annotate protein-coding genes and tRNAs. But it would be nice to have snoRNA reasonably annotated as well.
Thanks gain and have a great day!

Best,
Jia-Xing
