I am trying to do principle component analysis, my file size is 1,5GB. It has been not responding past 30 mins, but I decided not to close the program, is it running or I am just waiting for nothing?

  • 1.5 GB is a huge file, I wouldn't be surprised if it runs for a good few hours! If you access your Task Manager (right-click the bottom toolbar on the Desktop) and look for process qgis-bin.exe, if there's a high value in the CPU column then it often means that it's processing data. You may just need to wait it out. – Joseph Jan 18 '16 at 11:48
