Hi there, I have a big amount of "lists" of data, each one with dimension 1024x1024. When I save it in an ASCII file (using "write" function) it take about 15 minutes. As I need run about 500,000 times this same routine, and I would like to do this save task in a fast way. In fact I will use these output files in another program that read ASCII or RAW/Generic Binary (8bits) formats. Each value from my lists ranges from 1 to 200 (integer values). Help, please.
