WDQ
Opening wdq (windaq) files in Python can be done with this library. Save it in the same folder as your script or in a python standard folder. Following examples assume a data file called 'SAMPLE.WDQ' present in the same folder.
reading line by line:
#!/usr/bin/env python import wdq data = wdq.Wdq("SAMPLE.WDQ") for l in data: print(l)
reading first ten samples:
#!/usr/bin/env python import wdq data = wdq.Wdq("SAMPLE.WDQ") a = data.next(10) print(a)
reading all (remaining) samples:
#!/usr/bin/env python import wdq data = wdq.Wdq("SAMPLE.WDQ") a = data.next(-1) print("shape: "+str(a.shape))
downsampling a factor of five:
#!/usr/bin/env python import wdq data = wdq.Wdq("SAMPLE.WDQ") a = data.next(-1)[0::5,:] print("shape: "+str(a.shape))
taking only the first column:
#!/usr/bin/env python import wdq data = wdq.Wdq("SAMPLE.WDQ") a = data.next(-1)[:,0] print("shape: "+str(a.shape))
