Hello everyone, Im cureeently working on miRNA data and i need to know the known and novel mirnas present in my samples. im using mirdeep2 for mapping and quantification. Here mirdeep2 is asking input files colapse and maaped files which i have provided it which i got via mirddep2 mapper and genome file which i have downloaded from ncbi, after providing everything im getting error. Please, can anyone gere guide me through it. ---

Hi @Alok_Dubey This tutorial has very good example data, and a workflow template that you could adopt: [Whole transcriptome analysis of Arabidopsis thaliana](https://training.galaxyproject.org/training-material/topics/transcriptomics/tutorials/mirna-target-finder/tutorial.html) ---
