I'm trying to submit RNA-seq data to the ENA database. In order to upload the files, I have to insert the file name into the right spot of my submission spreedsheet. However, no matter how I write the path + name of the file into the slot, it gets deleted after disabling the editor mode. What did I miss in the process? What do I have to change? The data comes from an extern harddrive, could that be an issue?
