Build beamformed data visualization tool #22

Open caseyjlaw opened 4 years ago

caseyjlaw commented 4 years ago

Libraries for reading/writing beamformed data.

Pick one that works for our needs and write a data quality visualization tool.

@greghell What do you like to use for filterbank visualization?

greghell commented 4 years ago

@caseyjlaw I simply use sigpyproc.Readers.FilReader

caseyjlaw commented 4 years ago

Could you share an example here? Or a link to github, if available. (I was planning on writing something new, but we have a tight deadline and should reuse code where we can.)

import sigpyproc from sigpyproc.Readers import FilReader import matplotlib.pyplot as plt import numpy as np

tmp = FilReader("/home/user/vikram/scratch/fil_B0531+21_1.fil").readBlock(0,1024); plt.figure() plt.subplot(121); plt.imshow(tmp,aspect='auto');plt.xlabel('frequency channel');plt.ylabel('time index');plt.colorbar(); plt.subplot(122); plt.plot(np.mean(tmp,1));plt.grid();plt.xlabel('frequency channel');plt.ylabel('power spectral density [arb. unit]'); plt.show()

Hi @greghell, I was reviewing our project plans and saw this issue. Do you think the visualization of filterbank/beamformed data is done? Or do you think it would be useful to build something more general than the plotting you described above?
