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
