How to filter "only Mrna "s from total RNA ?

Question

[XBria]

Hi everyone,

I am working with a data set of total rna. Already extracted a list of Biomart from ensemble website (gene stable IDs , gene Type, and Gene name). Need to only extract the Mrna s of the data to do DEG analysis. Please let me know which IDs are for mrna and how may I chack them ?

thanks,
