I currently am using a File SOP and a GEO_IOTranslator to read in a custom data file. However, I'd like the user to be able to edit some parameters when reading in the file, so I would like to create a custom File-like SOP. How would I go about doing this?
I'm trying to create a SOP based on SOP_Star.C, but that's probably not the best resource. How do I load and read a file? Could you point me at some examples to look at?
