Dear All, do you have any idea about how could I see N50 statistic after denovo assembly via rnaviralSPades in Galaxy Europe?. I have already tried to include log, contigstat and scaffoldstat options as output during the analyses however there is no information about N50 statistics in output files. ![rnaviralSPades_N50](https://us1.discourse-cdn.com/flex020/uploads/galaxy/original/2X/4/4f1ba22b4d536f7405a12299d37ed74fe81a50ab.png) ---

Welcome, @Serkan_ONDER Would a tool like **Quast** produce what you want? Another tool I can think of is **BlobToolKit** (visualization of statistics that include N50). Both of those tools link to assembly tutorials, or you can review here directly → [Assembly / Tutorial List](https://training.galaxyproject.org/training-material/topics/assembly/). Those with QC or Quality Control in the title, plus others have QC steps along with the longer protocols. Others are welcome to suggest more 🙂 ---

Dear @jennaj , Thank you so much for these great tools. I tried Quast just. It will be enough for me. Thanks 🙂 ---
