Hi, sorry for the confusion I understood that the Real(8) I'm using correspond to dtype float64 in Python. With the second method it seems to work but I get a wrong number of elements.
They should be grouped by 21 float64 but I don't find a number of data = 21*m where m is an integer number. I think the problem is that Fortran write 4bytes at the beginning and at the end of each file. I found a way to remove the first 4 bytes but not the last. Do you have any suggestion?
