Hi all, I have converted an ENVI image file into ASCII. The ASCII file has NaNs or NoData in them. I am not able to read the file into python since it is not able to recognize NaN. I'm not an experience python user, and hence i guess i'm not able to figure it out. Does anyone have any idea as to how i can import an ASCII file with NaNs in them ? [jv] I'm not sure this is applicable, but have you looked at the numpy extension package which has support for NaN? Hoping to hear from you, Raghu
