I have noticed there are several different annotations of circular RNAs. For example the same circular RNA from a human species can be written as:
hsa_circRNA_000167
hsa_circ_0000518
The difference is in the name, the length of the number and in the number itself. And I have found even a third version from circRNADb database that contains a number consisting of 5 characters in the end. Again some articles just name the circular RNA with no information on the circular RNA ID.
Since it is hard to compare results and find information from articles that use just one annotation, I would like to find a "converter" between different annotations or a database/file containing all the different annotations of circular RNAs.
Does anyone know any information regarding this issue?
Thank you very much!
Kind regards,

Actually this is an annotation problem regarding RNA-Seq data annotation, but you can find different aliases with different transcript to the same circularized ncRNA, one of databases that could help is Circ2Traits
http://gyanxet-beta.com/circdb/, http://www.circbase.org also could provide limited aliases of the same circular RNA transcript

As redundancy and annotation of circular RNAs is a real issue. We should always stick to the genomic location rather than fancy names.
Here, I had published a dataset that I had curated couple of years ago you can access it through this site

Agilent platforms that are usually used by researchers generate the circRNA id and we often use the coordinates to convert to circbase iD
You can also search for your circRNA using both ids in this simple website.
@Mohammad, I wondered if you have any idea which annotation works better for various databases that predict/store miRNA-circRNA interactions?
