Error in name duplicate for miRNA differential analysis

Question

[enola.missonnier]

Hello everyone,

I'm analysis miRNA sequencing data, I already performed all the steps until the read count output from miRDeep2. I used the files miRNAs_expressed_all_samples.csv, and I merged all samples in one table, with col names my samples and as row names the miR.

But now I'm having problem regarding duplicate, I sometimes have the same miR but from a different precursor, is there any way to change the name like for mRNA with ENS number for example?

I will be glad if someone can figure out with this problem that blocking me for the rest of my analysis!

Thank you in advance!
