Hello,

I'm trying to download MesAur2.0 data and have difficulties with it either using the command line or through a web browser. I can clearly see the genome with gene annotation on the web but when I follow the link with genome data the only hamster I can find is a Chinese hamster.

Would you be so kind as to point me in the right direction to get fasta and gtf files?

Thank you so much!
Marianna

Hello, Marianna.

Thank you for your question about downloading data from the UCSC Genome Browser. 

The MesAur2.0 assembly you're referring to is provided as an assembly hub by an external collaborator, the Siomi lab at Keio University School of Medicine. I've cc'd their contact email in my response. Hopefully they can provide you with the FASTA and GTF annotation files for this assembly. 

If you have any further questions, please reply to gen...@soe.ucsc.edu. All messages sent to that address are archived on a publicly-accessible Google Groups forum. If your question includes sensitive data, you may send it instead to genom...@soe.ucsc.edu.

Dear Matthew,
Thank you so much for your reply!

Dear Dr. Siomi,
Would you be so kind as to share FASTA and GTF files for MesAur2.0 assembly? Presently I'm working on the smell loss caused by Covid-19 infection using hamster as a model. I'm trying to visualize some ATAC-seq data, but I was using the MesAur1.0 assembly which is not compatible with the UCSC Genome browser.

Thank you so much,
Best regards,
Marianna

Hello Mariana,

 

I am a former grad student in Siomi lab and replying to you on a behalf of Dr. Siomi. Sorry for your inconvenience, but you can download data from our website. http://siomilab.med.keio.ac.jp/?page_id=26.

Or from this link

[golden hamster genome sequence] MD5:c575be09457eaac35d4fe98d80254d53
[golden hamster gff3 annotation] MD5:24c1cfb0ba0c9d20a171d7610fae4ae7
[golden hamster transposon annotation (repeatmasker .out file)] MD5:dbacf099e330b419238c1deaed3ae5ac

 

Let me know if there are any problems with downloading these data, and we would be happy if you could cite Ishino K et al, NAR 2021 when you use this data.

 

Best,

Chikara

Hi Chikara,

Thanks a million for sharing the files! I really appreciate it.

Just a few more questions: i) what is N50 for genome fasta or is it of chromosome length sequences? ii) which pipeline did you use to annotate genes?
I have built up a chromosome length scaffold fasta file using PacBio data from MesAur1.0 assembly and my own HiC data to obtain chromosome length scaffold assembly, but have difficulties with de novo transcriptome assembly (MAKER is my problem). So I'm curious to know which approach you took?

Thanks,
Marianna

Hi Marianna,

 

No problems! For your questions, you can find the details of this reference in the original article, Ishino K et al, NAR 2021 (https://academic.oup.com/nar/article/49/5/2700/6137370?login=true#231957800)

 

In short, this is a chromosome length scaffold(summarized in Table 1), and we use just liftover for gene annotation(see the Methods and materials section). Although our annotation is not de novo transcriptome assembly, we can see a good mapping rate with this annotation for in early embryo and ovary RNA-seq data.

 

Thanks,

 

Chikara
