It works only if I can find a value belonging to the dtype of the array that is meaningless in the context of my data. For example, if it is only composed of positive integers, then I can fill the missing values with -1. But in my case, I would like to write a string (empty string, actually) to the output file where values are missing. I can't do that with the ma.filled(value) method if my masked array dtype is an integer. What I would need is an equivalent of the genfromtxt function for writing. guillaume Le 07/09/2010 01:34, Pinner, Luke a écrit :

How about the masked aray filled method? eg numpy.savetxt(somefilename, somemaskedarray.filled(somevalue))

Hello, Is there a function like savetxt that can deal with missing values in masked arrays? I'd like to control the way the missing values are written to the file. Thanks, Guillaume
