I've got some RNA-seq data that mRNAs were purified using oligo-dt and sequenced via the MGI-SEQ-2000 platform. Also, some RNA-seq data produced by Illumina NovaSeq and Hiseq platforms. I'm going to analyze microRNA and long non-coding RNAs from these datasets, however, I'm not sure as the data didn't specifically generate for this kind of RNAs (miRNA and long non-coding RNA). Could you please let me know your idea? Is there any tool/pipeline for such cases?
