Hi Nikita, On line 91 you define `rply` to be a list of 16 empty lists, then on line 148 you try to write in a loop to 64 elements of `rply`. But there are only 16, so your script errors.
As an aside, you could achieve the same as: rply = [[],[],[], ....] with rply = [[] for i in range(16)] which would be somewhat more reader-friendly. Even better is probably to use a multi-dimensional numpy array, for this and all the Xcomplex_NN variables. Then you could do things like 2's complement conversion in one hit: my_array[my_array > (2**31 -1)] -= 2**32 For what it's worth, if you use the katcp_wrapper python package (part of the corr library), or casperfpga it might be easier to get data than using the katcp library directly. katcp_wrapper.FpgaClient.read() returns a binary string which you can directly interpret as 2's complement using struct.unpack with the '>l' format specifier (see https://docs.python.org/2/library/struct.html) or using numpy's frombuffer function. (see https://github.com/casper-astro/tutorials_devel/blob/master/ise/roach2/tut_spec/roach2_tut_spec.py for a casperfpga example, or https://github.com/casper-astro/tutorials_devel/blob/v2012/tut3/tut3.py for a katcp_wrapper example) In fact, casperfpga is smart enough that if you use a snapshot block in your design and appropriately set the data type to signed in simulink, your python will auto-magically interpret the data correctly. Hope that helps, Cheers Jack On Fri, 30 Aug 2019 at 07:04, 'Nikita Rathore' via [email protected] <[email protected]> wrote: > > Dear Casperites > > I am working on Roach2 and 5Gsps ADC1x5000-8. > > During data acquisition for 4 element interferometer I am having following > issue in python code.
