Basicly the question is in the title. Basically, I have a file in galaxy that contains all mouse genes but I need to remove genes so that I only have the genes related to glucose metabolism left. Does anyone have a good script or any idea how I should go about this? I thought about building a different file from scratch, using GO annotation (AmiGo2 search) but I dont even know which extension or in what program I should save the downloaded data... and then convert it into GAF or something. But yeah clearly I'm new at this so, please if someone could help me out that would be awesome.
