Get and annotation of isomiR profile from RNA-seq

Question

[caombrat]

Hi,

I should get and analysis isomiR profile from RNA-seq with FASTA format. The best Database for this, is the "DeAnnIso". But here is a problem with this Database. In the "DeAnnIso" you can upload the FASTA format with maximum size 50MB, but the size of my FASTA file is more than 1000MB. I try to compress the file in different ways and uploading, but it doesn't work.

Does anybody know any way to solving this problem?

Or Does anybody know any other easy way to get isomiR profile from RNA-seq with FASTA format?

Thank you very very much!
