I'm a bit confused on an error I keep running into. I didn't have it before, but at the same time my data was wrong so I had to re-write the code.
Running the following:
plt.figure(figsize=(20,10))
x = np.arange(1416, 1426, 0.009766)
gaverage = np.empty((21,1024), dtype = np.float64)
calibdata = open(pathc + 'calib_5m.dat').readlines()
#print(np.size(calibdata)) ||| Yields: 624
#print(np.size(calibdata)//16) ||| Yields: 39
calib = np.empty(shape=(np.size(calibdata)//16,1024), dtype=np.float64)
for i in range(0, np.size(calibdata)//4):
calib[i] = calibdata[i*4+3].split()
caverage = np.average(calib[i] ,axis = 0)
Yields this:
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-25-87f3f4739851> in <module>()
11 calib = np.empty(shape=(np.size(calibdata)//16,1024), dtype=np.float64)
12 for i in range(0, np.size(calibdata)//4):
---> 13 calib[i] = calibdata[i*4+3].split()
14 caverage = np.average(calib[i] ,axis = 0)
15
IndexError: index 39 is out of bounds for axis 0 with size 39
Now what I'm trying to do here is basically take every 4th line in the file read in calibdata and write it to a new array, calib[i]. If the indices are the same size how are they out of bounds? I think there's some fundamentally flawed logic here on my part so if anyone can point out where I'm falling short, that would be great.
calib is initialized to size (39,n). But i iterator goes well beyond that:
