I’m new to bioinformatics and am trying to learn how to use mothur. I installed it in my Windows PC and is now trying to input data files (from sequencing). I followed the MiSeq SOP, manuals and tutorials, but I keep getting errors such as files/directory cannot be found or not writable. I am kind of lost how to get the directory and input files together, whether in the command line or interactive mode. Please help! Thank you very much.
