The data-element is a float-number and no sequence (I think). But I get the error "setting an array element with a sequence".
folder = r"C:\Dokumente und Einstellungen\ssc"
contents=os.listdir(folder)
ar = zeros((81,81,256),int)
filenumber = 0
for d in contents:
if str(".bin") in d:
filename = os.path.join("C:\\Dokumente und Einstellungen\\ssc\\" + d)
print filename
c_file = open(filename,"rb")
for k in range(8): #81
for m in range(2): #256
data = unpack('d',c_file.read(8))[0]
print data
ar[filename,k,m] = data
filenumber += 1
