• File
  • Browse Folder: Reopens a closed Folder Browser, or brings the window to the front.
  • Exit: Exits SpectraFox, and closes all windows.
• Windows: keeps track of all currently opened windows in SpectraFox
• GPU Computing
  • Settings: Opens a window to set up the GPU preferences. Requires OpenCL or CUDA packages to be installed. This setup is recommended for some non-linear fit-models, which gain a huge performance enhancement.
