[maker-devel] multiple overlapped snoRNA genes got annotated by maker

Fri May 26 07:54:44 MDT 2017

Hi Jia-Xing,

v2.31.9 may not have had that option. I know that it is in the v3.00.0 version, so you best option may be to update.

Thanks,
Mike

This option used to be there according to this post (https://www.biostars.org/p/217240/ <https://www.biostars.org/p/217240/>). I manually specified this option in my maker_opts.ctl file but I don't think maker has correctly recognized this option:

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 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!
